摘要： The invention is an indwelling endourethral catheter, which is structurally similar to prior art Foley catheters with an additional feature that overcomes the common problem of significant damage to the patient caused by unsafely removing the catheter from the body before actively deflating the anchoring mechanism. The additional feature is a tear zone, which is a location at which the walls of the catheter are weaker than the rest of the catheter walls, is designed to at least cause a tear or rupture in at least one of the walls of the catheter tube when the catheter is pulled proximally with a force large enough to cause an inflated anchoring member to be pulled out of the bladder. Embodiments of the catheter of the invention additionally comprise a recoil limiting member disposed between the tear zone and the urethral orifice outside the patient's body to prevent part of the catheter tube from remaining inside the patient©s body after the tube tears at a tear zone.
