  • Patent number: 8347887
    Abstract: An anastomosis device and related methods of using said device for reversing a female sterilization procedure. The anastomosis device can include a tissue approximation structure allowing for grasping and approximation of proximal and distal tube stumps remaining from the sterilization procedure so as to restore a lumen defined by the fallopian tubes for subsequent passage of reproductive cells. The anastomosis device can comprise a catheter body that is advanced through the reproductive tract, past the uterus and into the proximal stump. A flexible guidewire can guide a tissue approximation structure to the proximal stump wherein a set of proximal approximating structures are extended to grasp the proximal stump. The tissue approximation structure is then advanced into the distal stump wherein a set of distal approximating structures grasp the distal stump and cause the proximal and distal stumps to be brought into contact so as to commence biological healing.

  • Patent number: 8276591
    Abstract: A method of preventing inadvertent inflation of an implantable prosthetic includes biasing a valve assembly such that an outlet is substantially closed and using inadvertent pressure increases from the inlet to supplement the biasing of the valve assembly. It may further include the step of preventing fluid flow through the outlet by selectively varying fluid pressure within a bypass passageway having a first end which is in fluid communication with an inlet and a second end which is in fluid communication with a chamber. And, may also additionally include the step of displacing a flexible abutting wall disposed between the chamber and the valve assembly so that the abutting wall is caused to contact the valve assembly and urge the valve assembly into a closed position when the fluid pressure within the chamber exceeds a predetermined amount.

  • Patent number: 8211005
    Abstract: A method of treating pelvic organ prolapse is provided. The method generally includes the steps of establishing a first pathway between the external perirectal region of the patient to the region of the ischial spine in tissue on one side of the prolapsed organ, followed by establishing a second pathway in tissue on the contralateral side of the prolapsed organ. A support member, which includes a central support portion and two end portions, is positioned in a position to reposition said prolapsed organ in said organ's anatomically correct location. The end portions of the support member are introduced through the respective tissue pathways, followed by adjustment of the end portions so that the support member is located in a therapeutic relationship to the prolapsed organ that is to be supported.

  • Patent number: 8195296
    Abstract: Apparatus is provided, including an implantable mechanical support, shaped to support a portion of a urethra of a patient. One or more electrodes are coupled to the mechanical support, so as to contact tissue of the patient when the mechanical support is implanted in the patient. A control unit drives the electrodes to apply a current to the tissue. A method for treating a patient is also provided, including implanting a mechanical support in a position that supports a urethra of a patient. In response to increased pelvic pressure of the patient, a substance stored in a portion of the mechanical support that is not under the urethra is moved to a portion of the mechanical support that is under the urethra. Other embodiments are also described.

  • Patent number: 8109866
    Abstract: A pelvic implant having a central support portion, and a plurality of extension members, is provided. The extension members can be positioned or extend from the central support portion in opposing pairs. The extension members are generally attached to the central support portion at respective junctions (e.g., via rivets), and sheaths or covers can be employed to cover at least a length or portion of the extension members. Further, one or more spanning members can extend from a first of the opposed and paired extensions to the opposing extension, e.g., under or across the central portion and the respective junctions to provide additional tensile strength for the implant during deployment or implantation.

  • Patent number: 8066725
    Abstract: An anastomosis device providing increased functionality, reliability and safety through the use of designs addressing potential puncture of an inflation balloon being used to hold and approximate tissue. The anastomosis device can include bladder retention structures configured to engage and retain tissue without pointed or sharpened surfaces that can rupture the inflation balloon. The anastomosis device can include a reinforced or otherwise protected inflation balloon to resist puncturing by a bladder retention structure. The anastomosis device can include a catheter wall profile selected to physically prevent bladder retention structures from being forcibly bent back so as to avoid potential contact with and puncture of the inflation balloon. The anastomosis device can include a catheter funnel with an internal spring for preventing kinking of the catheter lumen while providing for flexibility and stretch of the funnel to absorb pulling or shock force which can rupture the inflation balloon.
