  • Medical punch and surgical procedure
    Patent number: 7258694
    Abstract: A medical punch includes a longitudinally dividable anvil with a reduced cross-sectional dimension facilitating insertion of the anvil into the vessel wall to achieve a clean aperture in the vessel wall by cooperative shearing action of a cutting edge and an anvil edge. In another embodiment, the instrument incorporates a measuring device for determining the thickness of a vessel wall between an anvil and a distal end of a cylindrical structure which together form a caliper, and the measuring device can also constitute a medical punch by cooperative shearing action of a cutting edge and an anvil to achieve a clean aperture in the vessel wall.

  • Temporary anastomotic seal and method
    Publication number: 20060079915
    Abstract: Forming a proximal anastomosis on an aortic wall includes method and instrumentation and apparatus for forming an aortic puncture and inserting into the vessel through the puncture a fluid-impervious sealing element with a protruding retainer. An anastomosis of a graft vessel over the puncture is partially completed with the retainer of the sealing element protruding through the partial anastomosis. The retainer facilitates removal of the sealing element from the partial anastomosis prior to completion of the procedure.

  • Methods using a dual balloon telescoping guiding catheter
    Publication number: 20050119567
    Abstract: A guiding catheter comprises an outer guide having a guide lumen and an annular balloon mounted to a distal end of the outer guide, and an inner guide movably disposed within the guide lumen of the outer guide, the inner guide comprising a fluted balloon mounted to a distal end of the inner guide. A method involves selectably pressurizing and depressurizing the annular balloon to control occlusion of fluid flow relative to the annular balloon, and selectably pressurizing and depressurizing the fluted balloon independently of pressurizing and depressurizing the annular balloon to permit perfusion of fluid flow relative to the fluted balloon and control anchoring of the fluted balloon within a generally tubular structure.
