  • Patent number: 5667615
    Abstract: An incontinence electrode for controlling urinary incontinence in women is made of alternating bands of conductive and non-conductive polymers molded to form a tubular body. Electrical receptacles, formed in the molding process at the interior circumferential surface of the conductive polymer bands, accept metal contacts attached to electrical leads to make a secure and durable, mechanical and electrical connection between the conductive polymer bands and the leads. The leads are coupled to a controller and carry electrical current to and from the metal contacts which then distribute the current to the conductive polymer bands to cause a contraction of the vaginal muscles responsible for controlling urinary incontinence in women.

  • Patent number: 5437619
    Abstract: A range-of-motion splint for applying relatively constant torque across a joint undergoing rehabilitative therapy. The splint includes a first brace section configured to engage a portion of a patient's body on a first side of a joint, and a second brace section configured to engage a portion of the body on a second side of the joint. A first arm extends from the first brace section and a second arm extends from the second brace section. The first and second arms are connected by a dual axis pivot mechanism for rotational motion about both a primary joint axis and a lateral axis generally perpendicular to the primary joint axis. A first spring-engaging mount is located on the first arm at a position spaced from the primary joint axis. A second spring-engaging mount is located on the second arm at a position spaced from the primary joint axis. An eccentrically mounted spiral spring has an inner end mounted to the first spring-engaging mount, and an outer end mounted to the second spring-engaging mount.

  • Patent number: 5431625
    Abstract: An iontophoresis controller is configured for connection to an iontophoresis electrode pair. The controller controls infusion of a selected dose of ionic drugs into a patient through the electrode pair during a treatment period. The controller includes an electrode driver channel having an electrode output configured for electrical connection to the electrode pair. The electrode driver channel delivers a substantially constant electrode output current at a selected treatment level through the electrode output during the treatment period. The electrode output current rises exponentially from approximately zero to the selected treatment level, remains at the selected treatment level during the treatment period, and then falls exponentially to approximately zero. A microprocessor controls operation of the electrode driver channel to generate the electrode output current during the treatment period.
