Power of Attorney

I, Daniel R. Marshak, the undersigned, hereby
constitute and appoint Steven McAllister, Mark D.
Perrin, Bradley Jacobson and
Elizabeth W. Fraser, and each of them individually, as
my true and lawful attorney-in-fact to:

1.  Complete and execute on my behalf, as a director
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-fact's 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
September 29, 2014.
