         RE:      MedAmicus, Inc. - Registration Statement on Form S-8

Ladies and Gentlemen:

         We have acted as counsel to MedAmicus, Inc., a Minnesota corporation
(the "Company"), in connection with the preparation and filing with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
of a Registration Statement on Form S-8 (the "Registration Statement") relating
to the registration by the Company of an aggregate of 13,000 shares of its
Common Stock, par value $.01 per share (the "Shares"), for its 1996 Non-Employee
Director and Medical Advisory Board Stock Option Plan.

         As such counsel, we have examined copies of the articles of
incorporation and bylaws of the Company, each as amended to date, minutes of
various meetings of the Board of Directors of the Company and the original or
copies of all such records of the Company and all such agreements, certificates
of public officials, certificates of officers and representatives of the Company
and others, and such other documents, papers, statutes, and authorities as we
have deemed necessary to form the basis of the opinion hereinafter expressed. In
such examinations, we have assumed the genuineness of signatures, the
authenticity of all documents submitted to us as originals and the conformity
with originals of all documents submitted to us as copies thereof. As to various
questions of fact material to such opinion, we have relied upon certificates of
officers and representatives of the Company and others.

         Based upon the foregoing, and subject to the qualifications and
limitations set forth herein, we are of the opinion that (i) the Shares have
been duly authorized, and (ii) when issued, delivered and paid for in accordance
with the applicable plan referred to in the Registration Statement, the Shares
will be validly issued, fully paid and nonassessable.

         We express no opinion with respect to laws other than those of the
State of Minnesota and the federal laws of the United States of America, and we
assume no responsibility as to the applicability thereto, or the effect thereon,
of the laws of any other jurisdiction.

         We hereby consent to your filing a copy of this opinion as an exhibit
to the Registration Statement and to its use as part of the Registration
Statement.

         We are furnishing this opinion to the Company solely for its benefit in
connection with the Registration Statement as described above. It is not to be
used, circulated, quoted or otherwise referred to for any other purpose. Other
than the Company, no one is entitled to rely on this opinion.

Very truly yours,

LEONARD, STREET AND DEINARD
PROFESSIONAL ASSOCIATION
