Trimedyne makes medical lasers and laser delivery equipment. Products include holmium "cold" lasers and neodymium:YAG thermal lasers. The company originally made lasers for invasive cardiovascular surgery; after new treatment techniques sapped demand for those products, the company refocused on other areas, principally orthopedics and urology. While the company is developing products for cosmetic surgery, neurology, and gynecology, its Cardiodyne subsidiary is investigating new cardiovascular applications (particularly for angina) using lasers. Trimedyne sells primarily through distributors in the US and in international markets, which account for almost 30% of its revenues
