I, Robert Langer, the undersigned, hereby constitute and appoint Bradley Jacobson, Robert Puopolo,
Elizabeth Fraser, and Abdullah Malik, and each of them individually, as my true and lawful
attorney-in-fact to:
1. Complete and execute on my behalf, as a stockholder and member of the Scientific Advisory Board
of InVivo Therapeutics Holdings Corp., a Nevada corporation (the Company), Forms 3, 4, or
5 required to be filed by me under Section 16(a) of the Securities Exchange Act of 1934, as amended
(the Exchange Act) and the rules and regulations thereunder;
2. Do and perform any and all acts for and on my behalf which may be necessary or desirable to
complete and execute any such Forms 3, 4 or 5 and timely file such forms with the U.S. Securities
and Exchange Commission and any stock exchange or similar authority; and
3. Take any other action of any type whatsoever in connection with the foregoing, which in the
opinion of such attorney-in-fact may be of benefit to, in the best interest of, or legally required
of me, it being understood that the documents executed by such attorney-in-fact on my behalf
pursuant to this Power of Attorney shall be in such form and shall contain such information as such
attorney-in-fact may approve in such attorney-in-facts discretion.
I hereby grant to each of such attorneys-in-fact full power and authority to do and perform all and
every act which is necessary, proper or desirable to be done in the exercise of any of the rights,
powers and authority granted in this Power of Attorney, with full power of substitution and
revocation, and I ratify and confirm every act that such attorney-in-fact lawfully performs or
causes to be done by virtue of this Power of Attorney and the powers and authority granted herein.
I acknowledge that the attorneys-in-fact appointed in this Power of Attorney, in serving in such
capacity at my request, are not assuming, and the Company is not assuming, any of my
responsibilities to comply with Section 16 of the Exchange Act or the rules or regulations
thereunder.
This Power of Attorney shall remain in full force and effect until I am no longer required to file
Forms 3, 4 or 5 with respect to my holdings or transactions in securities issued by the Company,
unless I earlier revoke this Power of Attorney in a signed writing delivered to the foregoing
attorneys-in-fact.
IN WITNESS WHEREOF, the undersigned has executed this Power of Attorney as of
December 30, 2011.
