ITEM 4.  CHANGE IN REGISTRANT'S CERTIFYING ACCOUNTANT.

     (a)  Effective on July 8, 2004, the independent accountant who
was previously engaged as the principal accountant to audit the
Registrant's financial statements, Silverman, Olson, Thorvilson &
Kaufman, Ltd., was dismissed.  The decision to dismiss this
accountant was approved by the Registrant's board of directors.  This
accountant audited the Registrant's financial statements for the
fiscal years ended May 31, 2000 and 1999.  This firm's report on
these financial statements was modified as to uncertainty that the
Registrant will continue as a going concern; other than this, the
accountant's report on the financial statements for those periods
neither contained an adverse opinion or a disclaimer of opinion, nor
was qualified or modified as to uncertainty, audit scope, or
accounting principles.

     During the fiscal years ended May 31, 2000 and 1999, and the
subsequent period preceding such dismissal, there were no
disagreements with the former accountant on any matter of accounting
principles or practices, financial statement disclosure, or auditing
scope or procedure.  In addition, there were no "reportable events"
as described in Item 304(a)(1)(iv)(B)1 through 3 of Regulation S-B
that occurred during the fiscal years ended May 31, 2000 and 1999,
and the subsequent period preceding the former accountant's dismissal.

     (b)  Effective on July 8, 2004, the firm of George Brenner,
C.P.A., was engaged to serve as the new principal accountant to audit
the Registrant's financial statements.  The decision to retain this
accountant was approved by the Registrant's board of directors.
During the fiscal years ended May 31, 2000 and 1999, and the
subsequent period prior to engaging this accountant, neither the
Registrant (nor someone on its behalf) consulted the newly engaged
accountant regarding any matter.

ITEM 5. OTHER EVENTS AND REGULATION FD DISCLOSURE.

     In the Form 8-K filed on August 28, 2003, the Registrant
incorrectly reported its name as "NVCN, Inc."  The correct name of
the company is "NVCN Corporation".

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS.

Exhibits.

     Exhibits included are set forth in the Exhibit Index pursuant
to Item 601 of Regulation S-B.

Securities Exchange Act of 1934, the Registrant has duly caused this
report to be signed on its behalf by the undersigned, thereunto duly
authorized.
