The AMS 700 Series Inflatable Penile Implant from American Medical Systems is operated with a pump. Squeezing the pump transfers fluid from an abdominal reservoir into cylinders implanted within the shaft of the penis, causing an erection. This erection can be turned on and off at the push of a button, but is specifically engineered to feel natural, according to American Medical Systems.
A more general technical name for this mechanism is a three-piece inflatable penile prosthesis. It is distinct from the two-piece inflatable penile prosthesis, which implants the fluid reservoir in the scrotum, along with the pump unit, rather than separately in the abdomen. Three-piece inflatable penile prostheses such as the AMS 700 are associated with stronger erections because of the greater volume of fluid available, according to WebMD.
The AMS 700 is an outpatient procedure and patients are typically discharged within 24 hours. However, it is recommended to wait 6 weeks before using the implant, as directed on the American Medical Systems website. Some things to consider before choosing to undergo the procedure include the possibility of infection and mechanical failure and the likelihood of pain during healing. The penis may have an altered shape following the procedure, or show visible scarring. Perhaps the most important consideration is that natural erections will be impossible following the implanting of the prosthesis, even with the use of Viagra.
