Abstract
A penile erectile system which is adapted to be surgically implanted in man for the treatment of erectile impotence includes at least one penile implant comprising an elongated, flexible cylindrical body adapted to be implanted in the corpus cavernosum of a penis, said body having a tip at one end and an anchoring stem at the other end and an intermediate section including a pair of inner and outer chambers substantially filled with fluid and connected by a passage. The body also includes internal pump means for transferring fluid into the inner chamber and a control valve for controlling pressure in the inner chamber. The inner chamber is non-distensible so that when it is filled and pressurized by transferring fluid thereto it becomes rigid and supports the penis in an erectile state.
