Surface-treated prostheses receive FDA approval

June 1, 2001

Minneapolis-American Medical Systems has received FDA approval for InhibiZone, an antibiotic surface treatment used on its AMS 700 series penile prostheses. The treatment is impregnated through a patented process into the tissue-contacting surfaces of the prostheses. In laboratory testing, the device elutes the drugs from the surface when exposed to a warm, moist environment, providing antibiotic action both on the surface and in a zone surrounding the treated device, according to the company.
