Problems solved by technology

[0007] As evidenced by clinical experience with the devices described above, it is difficult to teach patients to recognize and operate the small locking valves that are encased in and shielded by scrotal tissue
Additionally, it takes 3-5 minutes to refill the cuff through the fluid restrictor

Embodiment Construction

[0026] figure 1shows a hydraulic urethral closure device (HUOD) 1 implanted in a male body as shown. Hydraulic urethral closure devices are one-piece devices that are implanted through a perineal or penoscrotal incision. An inflatable hydraulic closure cuff 2 encircles the urethra and is permanently connected via a flexible tube to a control mechanism 3 implanted in the scrotum. The pressure compensator 4 is also permanently connected to the control mechanism 3 via a flexible catheter 10 so as to be able to be placed in the subcutaneous tissue of the abdomen, thigh or alternatively in the prevesical space. The closure cuff 2 is implanted in the unexpanded released state and left in place for approximately 6 weeks postoperatively to allow for healing and resolution of pain and edema. After this release time, the urologist activates the device by pressing the activation button 5 with the intact scrotal skin. In doing so, the closure cuff 2 is inflated to apply a preset 60-80 ...

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 de-activated (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.

Description

[0001] This invention was made under Government support under SBIR Lot No. R43DK092007-01 awarded by the National Institutes of Health. The government has certain rights in this invention. technical field [0002] The present invention relates to embodiments of hydraulic urethral closure devices (HUODs) that are fully inserted or surgically implanted in the body for controlling the lack of urinary (urinary) or fecal (bowel) restraint. These devices are commonly referred to as "artificial sphincters," which are installed in the body to supplement or replace the body's natural sphincter muscles. Background technique [0003] One such device manufactured by American Medical Systems, Inc. is the AUS800, a fully implantable hydraulic sphincter implanted in men and women with urinary incontinence that has been on the market for over 35 years. AUS800 and its predecessors are disclosed in US Patent Nos. 3,863,622; 4,222,377; 4,412,530; and 4,878,889. AUS800 consists of a silicone ...
