63. The device of claim 61, wherein the sealing element is ring-shaped and is formed of a resilient material.
64. A method for anastomosing a vascular conduit to a hollow body structure so that the vascular conduit is in fluid communication with the interior of the hollow body structure, the method comprising steps of:
forming an opening in tissue of a hollow body structure so that the opening passes into an interior of the body structure;
positioning an end of a vascular conduit against the tissue; and
attaching the vascular conduit to the tissue so that the vascular conduit is in fluid communication with the interior of the hollow body structure, wherein a sealing element is used to enhance the attachment between the end of the vascular conduit and the tissue.
65. The method of claim 64, wherein the end of the vascular conduit is positioned against the tissue, and the sealing element is positioned against the end of the vascular conduit to force the end of the vascular conduit against the tissue.
66. The method of claim 65, wherein the sealing element is a ring and the ring is positioned around the vascular conduit and forces the end of the vascular conduit against the tissue.
67. A method of carrying out a surgical procedure on a hollow body structure through which fluid is flowing, the method comprising steps of:
forming an opening passing through the hollow body structure, the opening extending from an exterior surface of the hollow body structure to an interior surface of the hollow body structure;
providing a tissue contacting member movable between collapsed and expanded orientations, the tissue contacting member being attached to an elongate support member;
positioning the tissue contacting member in said collapsed orientation through the opening and adjacent the interior surface of the hollow body structure;
moving the tissue contacting member into said expanded orientation and into contact with the interior surface of the hollow body structure; and
inserting an instrument through the opening and into the hollow body structure to carry out a surgical procedure on the hollow body structure, the tissue contacting member substantially preventing fluid flowing through the hollow body structure from escaping through the opening.
68. The method of claim 67, wherein the hollow body structure is a patient’s aorta, and the surgical procedure is carried out to anastomose a vascular conduit to the aorta.
