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.
