Abstract
An apparatus for insertion into the urethra for attachment to and removal of an in-dwelling urinary continence device comprises generally a tubular body having a longitudinal bore with a slidable shaft therein. Slidable jaws are connected to a first end of the shaft and are normally retained in a closed position within the bore. The shaft may be longitudinally displaced within the bore to cause the jaws to protrude therefrom and assume an opened position. A magnet, slidable within the jaws, protrudes from the jaws when they are in their opened position to attract a ferrous ball for retraction into the jaws. The apparatus employs a method for removing an intraurethral device wherein anchoring members holding the device in place may be collapsed and the device removed with a single insertion of the tool. The device may also be used for retrieving objects from body passages other than the urethra, for example, arteries.
