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.

Claims

1-15. -15. (canceled)

16. Apparatus for forming a temporary fluid-tight seal on the inner wall of a fluid conduit through an aperture therein within a patient'"'"'s body, the apparatus comprising a fluid-impervious flange having an outer periphery and a protrusion thereon disposed to protrude through the aperture in a wall of the fluid conduit for positioning the flange against the inner wall over the aperture, the flange including a balloon disposed to be inserted in deflated condition through the aperture for configuring the flange into sealing engagement against the inner wall covering the aperture in inflated condition and for selectively reconfiguring the flange in deflated condition for removal through the aperture.

17. Apparatus according to claim 16 including segments of the flange disposed about the protrusion for flaring radially outwardly against the inner wall in response to the inflated condition of the balloon.

18. Apparatus for forming a temporary fluid-tight seal on the inner wall of a fluid conduit through an aperture therein within a patient'"'"'s body, the apparatus comprising:

a fluid-impervious flange having an outer periphery and a protrusion thereon disposed to protrude through an aperture in a wall of the fluid conduit for positioning the flange against the inner wall over the aperture, the flange including a plurality of ribs radially disposed about a distal end of the protrusion, and including a web of flexible material disposed about the plurality of ribs for configuring the fluid impervious flange into sealing engagement against the inner wall of the fluid conduit, and for selectively reconfiguring the flange in deflated condition for removal through the aperture.
