The AMS 700^TM Series prostheses are fluid-filled systems each consisting of a pair of cylinders, an inflate/deflate pump, and a fluid-filled reservoir. The components are connected by kink-resistant tubing.

During surgery, the reservoir is implanted in the lower abdomen, the pump is placed in the scrotum and the two cylinders are implanted in the corpora cavernosa (the chamber of the penis that, when filled with blood, normally produces an erection). The system is filled with sterile saline solution and then connected to form a closed system, completely concealed in the body.

• To inflate the device and achieve an erection, simply squeeze the pump bulb several times.
• This causes the saline solution to move from the reservoir, through the tubing and into the cylinders. Fluid moving into the cylinders replicates the body's natural process of blood flowing into the penis. This process creates full rigidity as the cylinders are inflated.
• To deflate the device, you press and hold the release valve portion of the pump.
• This transfers saline solution back into the reservoir, making the penis flaccid.
