The present invention provides An implantable girth device for controlling urinary incontinence comprising: an adjustable resilient circumferential collar 1 for surrounding the urethra; said collar comprises: i. a strap 10 for snugly embracing said urethra, said strap comprising an inner surface 5 and an outer surface 2; ii. a first inflatable/deflatable expandable flexible elastic member 3 for limiting expansion of the lumen of said urethra affixed to portion of said inner surface 5 of said collar; iii. a second inflatable/deflatable expandable non elastic reservoir 4 affixed to portion of said outer surface 3 of said collar 1; said expandable reservoir comprises a fluid; and, iv. a valve for fluidly communicating said first inflatable/deflatable expandable flexible elastic 4 member with said second inflatable/deflatable expandable non elastic reservoir 4; wherein said collar pressure upon said urethra is increased or decreased with sensed urethra pressure such that when urethral pressure is exerted against said strap said first expandable member affixed to said strap is deflated by transferring said fluid through said valve to said second expandable reservoir resulting in continence such that urine remains in said urethra for about 1.5 seconds; further wherein when urethral pressure decreases, said second expandable reservoir transfers said fluid to said first expandable member such that both said second expandable reservoir and said first expandable member are approximately resuming their original shape. |
