Temporary anastomotic seal and method

摘要

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.

主权项

1. An apparatus for forming a temporary and substantially fluid-tight seal on an inner wall of a fluid conduit within a patient's body, the apparatus comprising:
a substantially fluid-impervious flange comprising an outer periphery and a stem, wherein the flange comprises a tube of polymer material with a tensile member disposed in the tube, wherein adjacent convolutes of the tube are attached to one another by adhesion to form the flange and wherein the flange is configured to be selectively disassembled between the adjacent convolutes.
