Abstract
An indwelling urethral catheter system and method of its use involve a drainage shaft (16) mounted in a urinary tract (24) having an externally-operated, normally-closed, fluid valve (38) mounted therein near the meatus (22) of the urinary tract. A removable insertion conduit assembly (12), separate from the catheter drainage shaft, is for extending from outside the body, through the meatus of the urinary tract to plug into the proximal end of the catheter drainage shaft and impinge on the valve for holding it open to allow free drainage through the valve. Once the insertion conduit is removed from the urinary tract it no longer impinges on the valve for holding it open and the valve is thereafter normally closed unless opened by application of force from outside the body.
