EXHIBIT 24
POWER OF ATTORNEY

		I, Susan E. Knight, hereby authorize and designate each of
 John Manders, Timothy Arens, Nicole J. Leimer, and Amra Hoso signing
 singly, as my true and lawful attorney-in-fact to:

	(1)	execute for and on my behalf, in my capacity as an officer and/or
 director of Surmodics, Inc., a Minnesota corporation (the "Company"), the
 Forms 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;

	(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 4 or 5 and
 timely file such form with the Securities and Exchange Commission, any stock
 exchange or similar authority, and the NASDAQ Stock Market; 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 substitutes 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.

		This Power of Attorney shall remain in full force and effect until
 I am no longer required to file Forms 4 and 5 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 either a partner or employee of Faegre Baker Daniels LLP, or an employee
 of the Company, 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 under Section 16 of
 the Exchange 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 12th day of February, 2020.
