  • Patent number: 6460541
    Abstract: An inflatable structure comprising an inflation compartment defining an enclosed interior volume and an anti-reflux valve having an outlet end positioned in the interior volume. The anti-reflux valve includes an elongate inflation passage including opposedly facing film layers that are bonded to one another at their edges to form an interior gas flow channel. The elongate inflation passage is bonded to the inflatable compartment to form an opening for introduction of gas into the passage, for inflation of the inflation compartment, and arranged so that upon termination of gas flow into the interior volume, after pressure in the interior volume has been raised above exterior pressure on the inflatable compartment, gas pressure in the interior volume collapses the opposedly facing film layers against one another to form a seal against the interior volume gas pressure and maintain the inflation compartment in an inflated state.

  • Patent number: 5861431
    Abstract: The present invention provides a method of treating incontinence in a patient that has a bladder and a urethra. The urethra forms a lumen for draining the bladder. The method comprises the steps of delivering an agent into the lumen and passing the agent from the lumen to internal body tissue. The agent increases restriction of the lumen thereby providing increased control over urine flow from the bladder.

  • Patent number: 5640976
    Abstract: A rolling incontinence plug partially or fully inserted within a urethra has an anchor to restrict its insertion into the urethra. The anchor is configured to be placed between a vestibule and labia minora for restricting insertion of the incontinence plug. The outer circumference of the anchor easily conforms to the shape of the vestibule and responds to varying pressure of the labia minora as the patient moves. Further, because the anchor naturally conforms to the vestibule, no additional artificial substances or devices are needed to secure the anchor.

  • Patent number: 4807608
    Abstract: A mechanical penile prosthesis is disclosed. The prosthesis includes a sleeve that encapsulates a linear assembly of cups, an actuating means and a cable. The linear assembly of cups allows the prosthesis to be bent from an erect position to a flaccid position. The actuating mechanism includes a biasing member, a poppet with first and second shoulders, one or more sliding rings, and a flexible tine. Bending the prosthesis from its erect position to its flaccid position causes the poppet to move toward the distal end of the prosthesis, allowing the tines to lock behind the second shoulder. To return the prosthesis to its erect state the prosthesis is bent further until the sliding ring separates the tines, allowing the biasing member to force the second shoulder past the tines; the tines snapping back into a position on the proximal side of the first shoulder.
