Power of Attorney

I, Jeffrey S. Hatfield, the undersigned, hereby constitute and appoint Steven
McAllister, Mark D. Perrin, Tamara Joseph, Leora Rodenstein, Rosemary Reilly,
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, and 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 and 5 and any amendment
or amendments thereto, and timely file such forms with the U.S. Securities and
Exchange Commission (the "SEC") and any stock exchange or similar authority,
including without limitation the filing of a Form ID or any other application
materials to enable me to gain or maintain access to the Electronic Data
Gathering, Analysis and Retrieval system of the SEC; and

3.Seek or obtain, as my representative and on my behalf, information regarding
transactions in the Company's securities from any third party, including
brokers, employee benefit plan administrators and trustees, and I hereby
authorize any such person to release any such information to such
attorney-in-fact and approve and ratify any such release of information; and

4.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 or relieving, and the
Company is not assuming or relieving, any of my responsibilities to comply with
Section 16 of the Exchange Act or the rules or regulations thereunder.
I acknowledge that neither the Company nor the foregoing attorneys-in-fact
assume (i) any liability for my responsibility to comply with the requirements
of the Exchange Act, (ii) any liability of mine for any failure to comply with
such requirements, or (iii) any obligation or liability of mine for profit
disgorgement under Section 16(b) of the Exchange Act.

This Power of Attorney shall remain in full force and effect until I am no
longer required to file Forms 3, 4 and 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
November 3, 2016.
