Abstract
A totally implantable method for occluding the urethra or bladder neck utilizing an occlusive cuff connected to a control mechanism via a conduit tube. The occlusive cuff is reversibly changed from an activated (occlusive condition) to a deactivated (non-occlusive) condition by depressing a deactivation button contained within a resilient, elastomeric sheath surrounding the control mechanism. The occlusive condition is once again obtained by depressing an activation button also situated within the resilient sheath. In the occlusive condition, a preset tension is applied to a flexible diaphragm through a tensioning suture by a constant force spring contained within the control mechanism. This tension is translated into an occlusive pressure applied to the urethra or bladder neck sufficient to prevent urinary leakage.
