  • Penile clamp for impotence
    Patent number: 5336157
    Abstract: This invention is a therapeutic clamp intended to help males with impotence, or what should be more properly called, erectile dysfunction. The clamp consists of two hinged rods having elastic bands causing the rods to exert pressure on the sides of the penis, thereby restricting flow of blood from the penis in order to maintain an erection without interfering with flow of blood into the penis, or obstructing the urethra.
