The present invention provides a urethral prosthesis including a substrate, an inflatable pillow attached to the substrate, a pressurized reservoir in fluid communication with the pillow and a restrictor. Upon compression of the inflatable pillow, inflating agent is transferred from the inflatable pillow to the pressurized reservoir. Upon terminating compression, inflating agent returns to the inflatable pillow. The urethral prosthesis may be implanted such that the inflatable pillow prevents unintentional voiding of a patient's bladder.

An implantable, adjustable male incontinence device. The device has an inflatable balloon affixed to a central portion of a reinforced nonextensible elastomeric strip. The balloon includes a first length of elastomeric tubing extending therefrom that provides fluid communication with the interior chamber of the balloon. The uninflated balloon is implanted to overlie the male urethra with the nonextensible strip oriented horizontally and facing away from the urethra. The lateral opposing ends of the nonextensible strip are sutured to the periosteum of respective left and right iliac bones and the inflation port is implanted beneath the skin in an accessible portion of the body, preferably in the scrotum or, less preferably, in the perineum. The inflation port, which also includes a second length of tubing in fluid communication therewith, is implanted beneath the skin and the first and second lengths of tubing are connected to one another. A fluid is injected into the inflation port and conducted to the interior chamber of the balloon causing it to inflate and force periurethral tissue against the urethra to partially constrict the urethra and reduce the pressure of urine on the external meatus. The urethral constriction can be adjusted by increasing or decreasing the amount of fluid in the balloon via the inflation port.

Lubricating gel compositions manufactured from water-soluble polymers and distilled water can prevent not only pregnancy but also sexually transmitted diseases (STDs) including AIDS due to their roles as physical blocking walls and spermicides. Colloidal silver, which has germicidal effects in a wide range, can be added to these compositions. These lubricating gel compositions, which are harmless and non-irritating to the male urethra, can be called “Urethral Condoms” because they act like condoms when injected into male urethras, and are easily eliminated from urethras by urination. They can also be called “Liquid Female Condoms” because they act like female condoms when injected into vaginas, and are easily eliminated from vaginas by vaginal irrigators and the vaginal scrubbing sponge of this invention.

Catheter-adapted briefs operative to stabilize an indwelling urethra catheter in a position of alignment with the natural orientation of the male urethral orifice to minimize catheter discomfort, prevent urine leakage, tissue damage, and reduce the frequency of urinary track infection.
