摘要： An intraurethral magnetic valve (1) for insertion in the human urethra of a person suffering from incontinence. The intraurethral magnetic valve (1) includes a nonferromagnetic cylindrical housing (2), a valve seat assembly (36) attached to one end of the housing, a spherical magnetic valve element (14) disposed for universal movement in the housing, and a ring (10) for retaining the valve element which is attached at the other end of the housing. The valve seat assembly (36) has a nonferromagnetic valve seat (4) and ferromagnetic ring (5). The valve element (14) is maintained in closed check position against the valve seat (4) by attraction to the ferromagnetic ring (5), restricting the flow of fluid through the valve (1). An external magnet (15) is used to impart magnetic torque and attraction to the valve element (14) displacing it from the valve seat (4) and opening the valve for fluid flow. On removal of the external magnet (15), the valve element (14) returns to its closed check position on the valve seat (4). The intraurethral magnetic valve (1) may further include a mechanism (14) having a spring (134) for relieving excessive fluid pressure, in which the valve seat assembly (36), rather than being attached to the housing (2), is axially slidable within the housing against the force of the spring (134) when excessive hydrostatic pressure is present to allow release of fluid through a passageway around the valve seat assembly (36).
