Stress Urinary Incontinence Treatment Device, Method and Tools

A device (10) for use within a woman's urethra for obstructing urine outflow when the pressure in the woman's abdomen is at or above a threshold pressure level (IAP1). The device (10) also allows urine outflow when the intra-abdominal pressure is below the threshold pressure level (IAP1). Device (10) includes a flexible tube (15) that is configured to be inserted into a urethra, wherein the tube (15) defines a lumen (14) that has inlet (19) and outlet openings. The tube (15) is configured to receive, conduct and discharge urine. The tube (15) is further configured such that the lumen (14) is at least partially obstructed when the pressure on the urethra surrounding the tube (15) at least meets the threshold pressure (IAP1), and the lumen (14) is more open when the pressure on the urethra surrounding the tube (15) is at a level below a second, lower, threshold pressure (IAP2).
