AMS 700 inflatable penile prosthesis with InhibiZone.
Inflatable penile prostheses are the definitive therapy for erectile dysfunction refractory to medical therapy. For years mechanical malfunction was the most common cause of device failure, but recent advances in design have largely eliminated this, and now infection is the most significant problem with these implants. Antibiotic-coated medical devices, such as central venous and bladder catheters, have proven effective in reducing bacterial colonization and biofilm formation, leading to decreased rates of infection. In 2001, American Medical Systems (AMS) released its AMS 700 series penile prosthesis impregnated with a proprietary combination of the antibiotics rifampin and minocycline, called InhibiZone. Multiple studies have found that this device significantly reduces infection rates in men receiving penile prostheses. In July 2009, the US FDA approved the AMS 700 with InhibiZone as the only inflatable penile prosthesis with clinical evidence showing significant reduction in the rate of revision surgery due to infection.
