HYDRAULIC URETHRAL OCCLUSIVE DEVICE

摘要

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.

1. An implantable occlusive system, comprising:
an implantable hydraulic occlusive device including:
an occlusive cuff;a control mechanism; anda pressure compensator,the control mechanism is in fluid communication with the occlusive cuff, through attachment via a flexible tube,the control mechanism is in fluid communication with an inner portion of the pressure compensator, through attachment via a flexible conduit,the control mechanism including an activation button and a deactivation button, the activation button upon depression, hydraulically inflates with hydraulic fluid the occlusive cuff to apply a preset occlusive pressure on the tubular body, the deactivation button upon depression, hydraulically evacuates the hydraulic fluid from the occlusive cuff to remove the preset occlusive pressure on the tubular body, the control mechanism also including a needle port; and a repressurization device for repressurizing the implantable hydraulic occlusive device including:
a needle configured to access the needle port of the control mechanism;an infusion tube in fluid communication with the needle;a pressure transducer in fluid communication with the infusion tube;a stopcock in fluid communication with the infusion tube; andan infusion syringe in fluid communication with the needle to deliver a solution to the control mechanism through the stopcock, the infusion tube, and the needle to repressurize the implantable hydraulic occlusive device,wherein the pressure transducer is configured to confirm an infused pressure in the hydraulic occlusive device.
