Trimedyne Announces Its Registration Statement, Covering Shares Sold in a Recent Private Placement and Other Shares, Is Effective

LAKE FOREST, CA -- (MARKET WIRE) -- January 18, 2007 -- Trimedyne, Inc. (OTCBB: TMED) today announced its Amended Registration Statement, covering 2,915,000 shares of common stock ("Shares") sold in a previously disclosed private placement, became effective January 17, 2007. The Amendment reflects the issuance of an additional 265,000 Shares to the investors.

The net proceeds of the private placement of about $3 million will be primarily used to finance the increased level of sales expected from the marketing of Trimedyne's new side firing laser fiber by Boston Scientific Corporation in the U.S. and Japan and by Lumenis, Ltd. elsewhere throughout the world, which is presently expected to commence late in the second calendar quarter of 2007.

The Amended Registration Statement also covers 212,000 Shares issuable under Warrants issued to two investment bankers, 600,000 Shares which may be issuable pursuant to options granted in the future under Trimedyne's 2007 Non-Qualified Stock Option Plan and other Shares which Trimedyne may be required to issue pursuant to anti-dilution provisions of the subscriptions for the privately placed Shares and the Warrants.

Please see the Amended Registration Statement on form SB-2, dated January 17, 2007, for more information on the private placement and Trimedyne's business.
