  • Patent number: 9452278
    Abstract: A system for implanting a catheter in a urethra. The system includes a catheter having a valve disposed at a distal portion of the catheter. The valve may be operable in response to an external magnetic field. The system also includes a tool having a tip member extending into an opening at the distal portion of the catheter to couple the tool to the catheter. the system also includes an element extending from the tool. The catheter has an internal path that provides a conduit for the element to be extended through the valve to engage a proximal portion of the catheter. The tool is adapted use the element to stress the catheter and stiffen the catheter along the length of the catheter. Stiffening the catheter facilitates implantation of the catheter in the urethra by enabling pull forces, push forces, and torque forces to be transmitted from the tool through the catheter to the proximal portion of the catheter without undue stress on the urethra.

  • Patent number: 8251400
    Abstract: A restraint system for a transportation vehicle may comprise a restraint member movably mounted to the vehicle. The restraint member may have a first leg and a second leg that travel together along opposite sides of a seat carried by the vehicle as the restraint member moves relative to the vehicle. A restraint harness may include a retractor that may be mounted to one of the first and second legs, and a lap web having one end mounted within the first retractor and an opposite end mounted to the other of the first and second legs. The lap web may be configured to restrain an occupant of the seat when the restraint member is moved to an occupant restraint position. At least one lock may be mounted to the vehicle and configured to secure the restraint member to the vehicle when the restraint member is in the occupant restraint position.

  • Patent number: 6066088
    Abstract: An intraurethral magnetic valve for insertion in the human urethra of a person suffering from incontinence. The intraurethral magnetic valve includes a nonferromagnetic cylindrical housing, a valve seat assembly attached to one end of the housing, a spherical magnetic valve element disposed for universal movement in the housing, and a ring for retaining the valve element which is attached at the other end of the housing. The valve seat assembly has a nonferromagnetic valve seat sealing surface and ferromagnetic ring, each having concentric apertures for passage of fluid. The valve element is maintained in closed check position against the valve seat by attraction to the ferromagnetic ring, restricting the flow of fluid through the valve. An external magnet is used to impart magnetic torque and attraction to the valve element displacing it from the valve seat and opening the valve for fluid flow. On removal of the external magnet, the valve element returns to its closed check position on the valve seat.

  • Patent number: 5366506
    Abstract: An urethral magnet valve for insertion into the urethra of a person suffering from incontinence defines a binary duct relief valve comprising a nonferromagnetic tubular housing containing a valve member of a permanent magnet encapsulated within a nonmagnetic material, enabled on a valve seat of high magnetic permeability ferromagnetic nature, by a magnetic attraction therebetween. Retaining flanges integral with the housing prevent escape of the valve element when valve is open. A manually held external positioned permanent switching magnet induces magnetic torque and attraction on the valve element causing it to rotate within the tubular housing lifting same from the valve seat opening the passageway therethrough and through urethra.
