Indwelling magnetically-actuated urinary catheter, and method of its construction

An indwelling magnetically actuable urinary catheter (35) involves the molding of a valve housing (32) to a catheter drainage shaft (16) by using a drainage-valve-cavity mandrel (22) and two inflation-valve-cavity mandrels (24). The drainage-valve-cavity mandrel (22) forms a spring seat having a bui...

Summary:An indwelling magnetically actuable urinary catheter (35) involves the molding of a valve housing (32) to a catheter drainage shaft (16) by using a drainage-valve-cavity mandrel (22) and two inflation-valve-cavity mandrels (24). The drainage-valve-cavity mandrel (22) forms a spring seat having a built in integral bypass and a valve seat. An elongated one-piece valve popper (50) of Ferro-magnetic material has an enlarged, rounded, bulbous head facing the valve seat and an elongated smaller diameter portion directed toward the spring seat for engaging the tapered spring supported by the spring seat.
