POWER OF ATTORNEY

  I, Jeffrey C. Smith, hereby authorize and designate each of Philip D. Ankeny,
Bryan K. Phillips, Douglas P. Long, Andrew G. Humphrey, and Alyn Bedford 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
3, 4 and 5 and any other necessary forms in accordance with Section 16(a) of the
Securities Exchange Act of 1934 (the "Exchange Act") and the rules and
regulations promulgated thereunder; and

  (2)  to file a Form ID on my behalf with the Securities and Exchange
Commission and to further 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 Securities and Exchange Commission, any
stock exchange or similar authority, and the NASDAQ Stock Market.

  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 3, 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 & Benson 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 7th day of January, 2011.
