Media file 11: This inflatable penile device has 3 major components. The 2 cylinders are placed within the penis, a reservoir is placed beneath the rectus muscle, and the pump is placed in the scrotum. When the pump is squeezed, fluid from the reservoir is transferred into the 2 cylinders, producing a firm erection. Squeezing the top of the pump causes a reversal of flow of the fluid from the cylinders back into the reservoir.
