Anastomosis method
First Claim
1. A method for sealingly joining a graft vessel to a target vessel at an anastomosis site, the target vessel having an opening formed therein, comprising the steps of:
- positioning a fastener comprising a deformable material radially adjacent a free end portion of said graft vessel, said material being transformable between a non-fluent state and a fluent state, upon application of energy to the material;
inserting at least said free end portion of said graft vessel in said target vessel through the opening in the target vessel;
supplying energy to the deformable material at an intensity sufficient to transform the material into said fluent state;
radially expanding at least said free end portion of said graft vessel and said fastener to expand the graft vessel into intimate contact with an inner wall of said target vessel; and
discontinuing the energy supply so that the material returns to its non-fluent state to sealingly secure the graft vessel to the target vessel.

Abstract
A method for sealingly joining a graft vessel to a target vessel at an anastomosis site, the target vessel having an opening formed therein. The method includes positioning a fastener made from a deformable material radially adjacent to a free end portion of the graft vessel. The material is transformable between a non-fluent state and a fluent state, upon application of energy to the material. The method further includes inserting at least the free end portion of the graft vessel in the target vessel through the opening in the target vessel. Energy is then supplied to the deformable material at an intensity sufficient to transform the material into the fluent state. The free end portion of the graft is radially expanded to expand the graft vessel into intimate contact with an inner wall of the target vessel. The energy supply is discontinued so that the material returns to its non-fluent state to sealingly secure the graft vessel to the target vessel.

26. A method for sealingly joining a graft vessel to a target vessel at an anastomosis site, the target vessel having an opening formed therein, comprising the steps of:
-
applying a coating comprising a curable material to a free end portion of said graft vessel, said material being transformable between a fluent state and a non-fluent state upon application of energy to the material; inserting at least said free end portion of said graft vessel in said target vessel through the opening in the target vessel; radially expanding at least said free end portion of said graft vessel to expand the graft vessel into intimate contact with an inner wall of said target vessel; and supplying energy to the material at an intensity sufficient to transform the material into its non-fluent state to sealingly secure the graft vessel to the target vessel. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. An anastomosis device for use in coupling an end of a first vessel to a side of a second vessel in an anastomosis, the device comprising a tubular member formed of a deformable material, and a graft vessel connected to the tubular member, the tubular member being transformable upon application of energy to the tubular member between a non-fluent state and a fluent state in which the tubular member is radially expandable to sealingly engage the graft vessel with the target vessel.
