EX-24
POWER OF ATTORNEY
       I, Lisa Wipperman Heine, hereby authorize and designate each of
 Brian Niebur, Jeffrey Ross, Joshua L. Colburn, Steven C. Kennedy,
Steven J. Conley, Elise B. Houser and Amra Hoso, signing singly,
 as my true and lawful attorney-in-fact to:
             (1)	prepare and execute for and on my behalf, in my
 capacity as an officer and/or director of Miromatrix Medical Inc. (the
 "Company"), a Form ID and Forms 3, 4 and 5 in accordance with
 Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange
 Act") and the rules and regulations promulgated thereunder and other
 forms or reports on my behalf as may be required to be filed in
 connection with my ownership, acquisition, or disposition of securities
 of the Company, including Form 144;
             (2)	do and perform any and all acts for and on my behalf
 that may be necessary or desirable to complete and execute any such
 Form ID, Form 3, 4 or 5 or Form 144, and any amendments to any of the
 foregoing, and timely file any such form with the 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 to my benefit, in my best interest, or legally
 required of me, it being understood that the statements executed by
 such attorney-in-fact on my behalf pursuant to this Power of Attorney
 shall be in such form and shall contain such terms and conditions as
 such attorney-in-fact may approve in such attorney-in-fact's
 discretion.
       I hereby further grant to each such attorney-in-fact full power
 and authority to do and perform any and every act and thing whatsoever
 requisite, necessary, or proper to be done in the exercise of any of
 the rights and powers herein granted, as fully to all intents and
 purposes as I might or could do if personally present, with full power
 of substitution or revocation, hereby ratifying and confirming all that
 such attorney-in-fact, or such attorney-in-fact's substitute or
 substitutes, shall lawfully do or cause to be done by virtue of this
 Power of Attorney and the rights and powers herein granted.  I hereby
 acknowledge that the foregoing attorneys-in-fact, in serving in such
 capacity at my request, are not assuming, nor is the Company assuming,
 any of my responsibilities to comply with Section 16 of the Exchange
 Act or Rule 144 under the Securities Act of 1933, as amended (the
 "Securities Act").
       This Power of Attorney shall remain in full force and effect until
 I am no longer required to file Form ID or Forms 3, 4 and 5 or Form 144
 with respect to my holdings of and transactions in securities issued by
 the Company, unless earlier revoked by me in a signed writing delivered
 to the foregoing attorneys-in-fact.  Notwithstanding the foregoing, if
 any such attorney-in-fact hereafter ceases to be at least one of the
 following: (i) an employee of the Company, (ii) a partner of Faegre
 Drinker Biddle & Reath LLP or (iii) an employee of Faegre Baker Drinker
 Biddle & Reath LLP, then this Power of Attorney shall be automatically
 revoked solely as to such individual, immediately upon such cessation,
 without any further action on my part.
       I hereby revoke all previous Powers of Attorney that have been
 granted by me in connection with my reporting obligations, if any,
 under Section 16 of the Exchange Act and Rule 144 under the Securities
 Act with respect to my holdings of and transactions in securities
 issued by the Company.
       IN WITNESS WHEREOF, I have caused this Power of Attorney to be
 duly executed as of this 3rd day of January, 2022.
