CALCULATION OF REGISTRATION FEE

(1)          Pursuant to Rule 416 under the Securities Act of 1933, as amended (the “Securities Act”), the securities being registered under this registration statement include such indeterminate number of shares of common stock that may be issuable by the registrant with respect to the securities being registered hereunder as a result of stock splits, stock dividends, or similar transactions.

Statement Pursuant to Rule 429(b)

The registrant is filing a single prospectus in this registration statement pursuant to Rule 429 under the Securities Act and the rules and regulations thereunder. Pursuant to Rule 429 of the Securities Act, the Prospectus contained in this Registration Statement is a combined prospectus and relates to a total of 587,950 shares of common stock, consisting of 192,234 shares of common stock being registered hereunder issuable upon the exercise of outstanding warrants and 395,716 shares of common stock issuable upon the exercise of outstanding warrants previously registered and not yet issued pursuant to the Registration Statement on Form S-3 (File No. 333-201535) (the “Prior Registration Statement”). This Registration Statement, which is a new registration statement, also constitutes a post-effective amendment to the Prior Registration Statement and shall become effective concurrently with the effectiveness of this Registration Statement in accordance with Section 8(a) of the Securities Act. The shares of common stock registered under the Prior Registration Statement were registered for issuance upon exercise of warrants issued in an offering of the Registrant’s common stock and warrants in May 2014 (the “2014 Offering”). Because the warrants included in the 2014 Offering had certain anti-dilution adjustments affecting the exercise price and the amount of shares of common stock issuable upon exercise of such warrants, we are filing this Registration Statement in order to register additional shares of common stock issuable upon exercise of such warrants as a result of anti-dilution adjustments.

PROSPECTUS SUMMARY

This summary highlights certain information about us, this offering and selected information contained elsewhere in or incorporated by reference into this prospectus. This summary is not complete and does not contain all of the information that you should consider before deciding whether to invest in our securities. For a more complete understanding of our company and this offering, we encourage you to read and consider carefully the more detailed information in this prospectus, including the information under the heading “Risk Factors” beginning on page 2 and the information incorporated by reference in this prospectus.

InVivo Therapeutics Holdings Corp.

We are a research and clinical-stage biomaterials and biotechnology company with a focus on treatment of spinal cord injuries (SCI). Our mission is to redefine the life of the SCI patient, and we are developing treatment options intended to provide meaningful improvement in patient outcomes following SCI. Our approach to treating acute SCIs is based on our investigational Neuro-Spinal Scaffold implant, an investigational bioresorbable polymer scaffold that is designed for implantation at the site of injury within a spinal cord contusion and is intended to treat acute spinal cord injury.  We believe the Neuro-Spinal Scaffold implant is the only SCI therapy in development focused solely on treating acute SCI directly at the epicenter of the injury. The Neuro-Spinal Scaffold implant incorporates intellectual property licensed under an exclusive, world-wide license from Boston Children’s Hospital and the Massachusetts Institute of Technology.  We are continually evaluating other technologies and therapeutics that may be complementary to our development of the Neuro-Spinal Scaffold implant or offer the potential to bring us closer to our goal of redefining the life of the SCI patient.

We currently have a clinical development program for acute SCI and a pre-clinical development program for chronic SCI.

Our leading product under development is our Neuro-Spinal Scaffold implant, an investigational bioresorbable polymer scaffold that is designed for implantation at the site of injury within a spinal cord contusion. The Neuro-Spinal Scaffold implant is intended to provide support to the surrounding tissue after injury, minimizing expansion areas of necrosis, and supporting endogenous healing/repair processes following injury. We expect the Neuro-Spinal Scaffold will be regulated by the FDA as a Class III medical device.

We are also developing our Bioengineered Neural Trails injection program for the treatment of chronic spinal cord injury.  Bioengineered Neural Trails are injectable combinations of biomaterials and neural stem cells delivered using minimally-invasive surgical instrumentation and techniques to create trails across the chronic injury site. We expect that our Bioengineered Neural Trails injection investigational product will be regulated by the FDA as a combination product.

We were incorporated on April 2, 2003, under the name of Design Source, Inc. On October 26, 2010, we acquired the business of InVivo Therapeutics Corporation, which was founded in 2005, and are continuing the existing business operations of InVivo Therapeutics Corporation as our wholly-owned subsidiary.

Our principal executive offices are located in leased premises at One Kendall Square, Building 1400 East, 4th Floor, Cambridge, Massachusetts 02139.  Our telephone number is (617) 863-5500.  We maintain a website at www.invivotherapeutics.com.  Information contained on, or accessible through, our website is not a part of, and is not incorporated by reference into, this prospectus supplement or the accompanying prospectus.

THE SECURITIES WE MAY OFFER

We are offering up to 587,950 shares of common stock issuable upon the exercise of outstanding warrants to purchase common stock.  The following briefly summarizes the general terms and provisions of our common stock and the warrants to purchase common stock pursuant to which such shares of common stock may be issued.  You should read the provisions of our articles of incorporation, as amended, our bylaws, as amended, and other relevant agreements relating to our securities before you make an investment decision with respect to our securities.

Description of Common Stock

The following is a description of our common stock.  It may not contain all the information that is important to you.  You can access complete information by referring to our articles of incorporation and bylaws.

Under our articles of incorporation, we have authority to issue 100,000,000 shares of common stock, par value $0.00001 per share.  As of March 31, 2016, there were 31,905,834 shares of common stock issued and outstanding.  All shares of common stock will, when issued, be duly authorized, fully paid and nonassessable.  Accordingly, the full price for the outstanding shares of common stock will have been paid at issuance and any holder of our common stock will not be later required to pay us any additional money for such common stock.

In addition, as of March 31, 2016:

·                  there were outstanding warrants to purchase an aggregate of up to 3,495,679 shares of our common stock at a weighted average exercise price of $8.03 per share;

The holders of common stock are entitled to one vote per share on all matters submitted to a vote of the stockholders, including the election of directors.  Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all shares of common stock that are present in person or represented by proxy. Except as otherwise provided by law, amendments to our articles of incorporation generally must be approved by a majority of the votes entitled to be cast by all outstanding shares of common stock.  Our articles of incorporation do not provide for cumulative voting in the election of directors.  The holders of common stock will be entitled to such cash dividends as may be declared from time to time by the board of directors from funds available.  The holders of common stock have no preferential or preemptive right and no subscription, redemption or conversion privileges with respect to the issuance of additional shares of our common stock.  Upon liquidation, dissolution or winding up of the company, the holders of common stock will be entitled to receive pro rata all assets available for distribution to such holders after

payment of our liabilities.

Description of Outstanding 2014 Warrants Pursuant to Which the Offered Shares of Common Stock May Be Issued

The following description summarizes the material terms and provisions of warrants issued by us on May 9, 2014 (the “2014 Warrants”).  Each 2014 Warrant currently has an exercise price of $3.87 per share, subject to adjustment pursuant to its terms as summarized below, and is exercisable at any time until 11:59 p.m. (New York time) on May 9, 2019. Each 2014 Warrant is currently exercisable for one share of common stock.

We have an existing Registration Statement on Form S-3 (File No. 333-201535), declared effective on February 10, 2015, that covers an aggregate of 7,000,625 shares of our common stock issuable upon the exercise of the 2014 Warrants, of which 395,716 shares have not yet been issued as of the date of this prospectus. The 2014 Warrants contained certain anti-dilution adjustments that were triggered by our sale and issuance of units on March 18, 2016, which units consisted of one share of our common stock and .50 of a warrant to purchase one share of our common stock (the “Unit Offering”). As a result of the Unit Offering, the exercise price of the 2014 Warrants was adjusted to $3.87 per share, and the number of shares issuable upon the exercise of the then outstanding 2014 Warrants was increased by an aggregate of 192,234 additional shares of our common stock.

The 2014 Warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). Unless otherwise specified in the warrant, the holder will not have the right to exercise any portion of the warrant if the holder (together with its affiliates) would beneficially own in excess of 4.99% (subject to increase or decrease by a holder to any other percentage not in excess of 9.99% upon 61 days’ prior written notice to us and any such increase or decrease will apply only to the holder sending such notice and not to any other holder of the warrants) of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants.

In the event that shares of common stock underlying the 2014 Warrants are no longer registered under the Exchange Act, the holder may, in its sole discretion, exercise the warrant in whole or in part and, in lieu of making cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, elect instead to receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the warrant.

Subject to applicable laws, the 2014 Warrants may be transferred at the option of the holders upon surrender of the warrants to us together with the appropriate instruments of transfer.

The exercise price and the number of shares issuable upon valid exercise of the 2014 Warrants are subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock, sales of our common stock at a price per share less than the exercise price then in effect (or securities convertible or exercisable into common stock at a conversion or exercise price less than the exercise price then in effect) and also upon any distributions of assets, including cash, stock or other property to our stockholders.

Upon the consummation of a “Fundamental Transaction” (as defined below), the holder of the warrant will have the right to receive, upon exercise of the warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such

6

Table of Contents

Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of shares then issuable upon exercise in full of the warrant without regard to any limitations on exercise contained in the warrant.

A “Fundamental Transaction” is defined in the 2014 Warrants as a transaction where (a) we, or any of our subsidiaries, directly or indirectly, in one or more related transactions (i) consolidate or merge with or into any other entity, (ii) sell, lease, license, assign, transfer, convey or otherwise dispose of all or substantially all of our respective properties or assets to any other person or entity, (iii) allow any other entity to make a purchase, tender or exchange offer that is accepted by the holders of more than 50% of the outstanding shares of our voting stock, (iv) consummate a stock or share purchase agreement or other business combination with any other entity whereby such other person or entity acquires more than 50% of the outstanding shares of our voting stock, or (v) (A) reorganize, recapitalize or reclassify our common stock, (B) effect or consummate a stock combination, reverse stock split or other similar transaction involving our common stock or (C) make any public announcement or disclosure with respect to any stock combination, reverse stock split or other similar transaction involving our common stock, or (b) any “person” or “group” (as these terms are used for purposes of Sections 13(d) and 14(d) of the Exchange Act and the rules and regulations promulgated thereunder) is or shall become the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% of the aggregate ordinary voting power represented by our issued and outstanding voting stock.

Except as otherwise provided in the 2014 Warrants or by virtue of such holder’s ownership of shares of our common stock, the holder of a warrant does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the warrant.

Registrar and Transfer Agent

The registrar and transfer agent for our common stock is Continental Stock Transfer & Trust Company.

Trading Market

Our common stock is traded on The NASDAQ Global Market under the symbol “NVIV.”

CERTAIN ANTI-TAKEOVER AND INDEMNIFICATION PROVISIONS OF

OUR ARTICLES OF INCORPORATION AND BY-LAWS AND NEVADA LAW

Anti-Takeover Effects of Provisions of Nevada State Law

We may be, or in the future we may become, subject to Nevada’s control share laws.  A corporation is subject to Nevada’s control share law if it has more than 200 stockholders, at least 100 of whom are stockholders of record and residents of Nevada, and if the corporation does business in Nevada, including through an affiliated corporation.  This control share law may have the effect of discouraging corporate takeovers.  We currently have less than 100 stockholders of record who are residents of Nevada.

The control share law focuses on the acquisition of a “controlling interest,” which means the ownership of outstanding voting shares that would be sufficient, but for the operation of the control share law, to enable the acquiring person to exercise the following proportions of the voting power of the corporation in the election of directors: (1) one-fifth or more but less than one-third; (2) one-third or more but less than a majority; or (3) a majority or more. The ability to exercise this voting power may be direct or indirect, as well as individual or in association with others.

7

Table of Contents

The effect of the control share law is that an acquiring person, and those acting in association with that person, will obtain only such voting rights in the control shares as are conferred by a resolution of the stockholders of the corporation, approved at a special or annual meeting of stockholders.  The control share law contemplates that voting rights will be considered only once by the other stockholders. Thus, there is no authority to take away voting rights from the control shares of an acquiring person once those rights have been approved.  If the stockholders do not grant voting rights to the control shares acquired by an acquiring person, those shares do not become permanent non-voting shares.  The acquiring person is free to sell the shares to others. If the buyer or buyers of those shares themselves do not acquire a controlling interest, the shares are not governed by the control share law.

If control shares are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of the voting power, a stockholder of record, other than the acquiring person, who did not vote in favor of approval of voting rights, is entitled to demand fair value for such stockholder’s shares.

In addition to the control share law, Nevada has a business combination law, which prohibits certain business combinations between Nevada corporations and “interested stockholders” for three years after the interested stockholder first becomes an interested stockholder, unless the corporation’s board of directors approves the combination in advance.  For purposes of Nevada law, an interested stockholder is any person who is: (a) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (b) an affiliate or associate of the corporation and at any time within the previous three years was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then-outstanding shares of the corporation. The definition of “business combination” contained in the statute is sufficiently broad to cover virtually any kind of transaction that would allow a potential acquirer to use the corporation’s assets to finance the acquisition or otherwise to benefit its own interests rather than the interests of the corporation and its other stockholders.

The effect of Nevada’s business combination law is to potentially discourage parties interested in taking control of the company from doing so if it cannot obtain the approval of our board of directors.

Anti-Takeover Effects of Provisions of Our Articles of Incorporation and Bylaws

Our articles of incorporation provide for a classified board of directors.  This provision could prevent a party who acquires control of a majority of our outstanding common stock from obtaining control of the board until our second annual stockholders meeting following the date the acquirer obtains the controlling stock interest.  The classified board provision could have the effect of discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us and could increase the likelihood that incumbent directors will retain their positions.  In addition, under our bylaws, directors may be removed only for cause and only by the affirmative vote of the holders of at least 80% of the voting power of our then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class.

Our bylaws also provide that stockholders may only act at meetings of stockholders and not by written consent in lieu of a stockholders’ meeting.  Our bylaws provide that stockholders may not call a special meeting of stockholders.  Rather, only the Chairman of the Board, the President or the board of directors pursuant to a resolution approved by a majority of the entire board of directors are able to call special meetings of stockholders.  Our bylaws also provide that stockholders may only conduct business at special meetings of stockholders that was specified in the notice of the meeting.  These provisions may discourage another person or entity from making a tender offer, even if it acquired a majority of our outstanding voting stock, because the person or entity could only take action at a duly called

Table of Contents

stockholders’ meeting relating to the business specified in the notice of meeting and not by written consent.

Indemnification of Directors and Officers

Nevada Revised Statutes (“NRS”) Sections 78.7502 and 78.751 provide us with the power to indemnify any of our directors, officers, employees and agents.  The person entitled to indemnification must have conducted himself in good faith, and must reasonably believe that his conduct was in, or not opposed to, our best interests. In a criminal action, the director, officer, employee or agent must not have had reasonable cause to believe that his conduct was unlawful.

Under NRS Section 78.751, advances for expenses may be made by agreement if the director or officer affirms in writing to repay the expenses if it is determined that such officer or director is not entitled to be indemnified.

Our bylaws include an indemnification provision under which we have the power to indemnify our directors, officers, former directors and officers, employees and other agents (including heirs and personal representatives) against all costs, charges and expenses actually and reasonably incurred, including an amount paid to settle an action or satisfy a judgment to which a director or officer is made a party by reason of being or having been a director or officer of the company.  Our bylaws further provide for the advancement of all expenses incurred in connection with a proceeding upon receipt of an undertaking by or on behalf of such person to repay such amounts unless it is determined that the party is entitled to be indemnified under our bylaws.  No advance will be made by the company to a party if it is determined that the party acted in bad faith.  These indemnification rights are contractual, and as such will continue as to a person who has ceased to be a director, officer, employee or other agent, and will inure to the benefit of the heirs, executors and administrators of such a person.  Our bylaws do not eliminate or limit the liability of a director for: (i) an act or omission which involves intentional misconduct, fraud or a knowing violation of law; or (ii) the payment of dividends in violation of NRS 78.300.  These provisions may be sufficiently broad to indemnify such persons for liabilities arising under the Securities Act, in which case such provision is against public policy as expressed in the Securities Act and is therefore unenforceable.

We maintain an insurance policy on behalf of our directors and officers, covering certain liabilities which may arise as a result of the actions of the directors and officers.

We have entered into an indemnification agreement with each of our officers and directors pursuant to which they will be indemnified by us, subject to certain limitations, for any liabilities incurred by them in connection with their role as officers or directors of the company.

* Estimated expenses not presently known.

Item 15.                               Indemnification of Directors and Officers.

Nevada Revised Statutes (“NRS”) Sections 78.7502 and 78.751 provide us with the power to indemnify any of our directors, officers, employees and agents. The person entitled to indemnification must have conducted himself in good faith, and must reasonably believe that his conduct was in, or not opposed to, our best interests. In a criminal action, the director, officer, employee or agent must not have had reasonable cause to believe that his conduct was unlawful.

Under NRS Section 78.751, advances for expenses may be made by agreement if the director or officer affirms in writing to repay the expenses if it is determined that such officer or director is not entitled to be indemnified.

Our bylaws include an indemnification provision under which we have the power to indemnify our directors, officers, former directors and officers, employees and other agents (including heirs and personal representatives) against all costs, charges and expenses actually and reasonably incurred, including an amount paid to settle an action or satisfy a judgment to which a director or officer is made a party by reason of being or having been a director or officer of the company. Our bylaws further provide for the advancement of all expenses incurred in connection with a proceeding upon receipt of an undertaking by or on behalf of such person to repay such amounts unless it is determined that the party is entitled to be indemnified under our bylaws. No advance will be made by the company to a party if it is determined that the party acted in bad faith. These indemnification rights are contractual, and as such will continue as to a person who has ceased to be a director, officer, employee or other agent, and will inure to the benefit of the heirs, executors and administrators of such a person.  Our bylaws do not eliminate or limit the liability of a director for: (i) an act or omission which involves intentional misconduct, fraud or a knowing violation of law; or (ii) the payment of dividends in violation of NRS 78.300.  These provisions may be sufficiently broad to indemnify such persons for liabilities arising under the Securities Act in which case such provision is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 17.                               Undertakings.

(a)                                 The undersigned registrant hereby undertakes:

(1)                                 To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)                                     To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii)                                  To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement.  Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii)                               To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)                                 That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)                                 To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)                                 That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i)(A)                    Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B)                               Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus.  As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.  Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(5)                                 That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)                                     Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)                                  Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)                               The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)                              Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

Table of Contents

(6)                                 The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7)                                 Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Re:          Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as legal counsel to InVivo Therapeutics Holdings Corp., a Nevada corporation (the “Company”), in connection with the registration statement on Form S-3, as amended (the “Registration Statement”), being filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), on the date hereof.

You have provided us with a draft of the Registration Statement in the form in which it will be filed with the Commission. The Registration Statement relates to the registration of 192,234 shares of common stock (the “Warrant Shares”) that are issuable upon the exercise of warrants to purchase common stock (“Warrants”) previously offered and sold by the Company on May 9, 2014. The shares registered in the Registration Statement are in addition to 395,716 shares of common stock previously registered and not yet issued pursuant to the Registration Statement on Form S-3 (File No. 333-201535), declared effective on February 10, 2015 (the “Prior Registration Statement”). Pursuant to Rule 429 of the Act, the prospectus contained in the Registration Statement relates to the common stock previously registered on the Prior Registration Statement as well as to the securities registered in the Registration Statement.

We have made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to our satisfaction of such documents, corporate records and instruments, as we have deemed necessary or appropriate for purposes of this opinion.  In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as copies.  As to facts material to the opinions, statements and assumptions expressed herein, we have, with your consent, relied upon oral or written statements and representations of officers and other representatives of the Company and others.  We have not independently verified such factual matters.

We are opining herein only as to the federal laws of the United States, the laws of the Commonwealth of Massachusetts, and the General Corporation Law of the state of Nevada, in each case as in effect on the date of this opinion, and we express no opinion with respect to the laws of any other jurisdiction or, in the case of Nevada, any other laws, or as to any matters of municipal law or the laws of any other local agencies within any state.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof, the Warrant Shares have been duly authorized by the Company and, when and to the extent issued in accordance with the terms of, and in the manner contemplated by, the Warrants, including the due and proper exercise of the Warrants and payment in full to the Company of the exercise price for the Warrant Shares as required thereunder, and as described in the Registration Statement, the Warrant Shares will be validly issued, fully paid and non-assessable.

This opinion is being delivered solely for the benefit of the Company and such other persons as are entitled to rely upon it pursuant to applicable provisions of the Act.  This opinion may not be used, quoted, relied upon or referred to for any other purpose nor may this opinion be used, quoted, relied upon or referred to by any other person, for any purpose, without our prior written consent.

We consent to your filing this opinion as an exhibit to the Registration Statement and to the reference to our firm in the Prospectus under the heading “Legal Matters.”  In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.
