ABSTRACT:
An artificial sphincter includes an implantable clamp which selectively pinches closed or opens a vessel in a living body. The clamp includes a spring member and a shape memory member that has a memory configuration. Either the vessel opening operation or vessel closing operation is effected by deforming the shape memory member from the memory configuration thereof, the other operation being effected by heat recovering the shape memory member to the memory configuration thereof. The shape memory member is heated by means of an AC source external to the body, the source inducing a heat-generating current, via a coil, in the shape memory member or in a resistive heater element which transfers heat to the shape memory element. The coil is preferably positioned near the surface of the body and is connected with leads to the shape memory member or resistive heater element which may be at a distance form the body surface. The clamp further includes a spongy inner layer which cushions the vessel and distributes the forces thereagainst.
