Anastomosis device and method
First Claim
1. A method of coupling a first vessel and a second vessel in an anastomosis, the method comprising the steps of:
- providing a first vessel with a fastener coupled thereto;
inserting at least a portion of the fastener into an opening formed in a side wall of the second vessel with an end portion of the fastener extending generally longitudinally within the second vessel; and
radially expanding at least a portion of the fastener to sealingly secure the first vessel to an inner wall of the second vessel.

Abstract
A method for coupling a first vessel and a second vessel in an anastomosis. The method includes providing a first vessel with a fastener coupled thereto, inserting at least a portion of the device into the second vessel with an end portion of the fastener extending generally longitudinally through the second vessel, and radially expanding at least a portion of the fastener to sealingly secure the first vessel to an inner wall of the second vessel. An anastomosis fastener for use in coupling the first and second vessels together is also disclosed. The second vessel has an opening formed in a side wall thereof for insertion of the device. The device includes a tubular member at least a portion thereof being radially expandable. The tubular member is preformed with a bend along its central longitudinal axis so that a portion of the tubular member extends out from the side wall of the second vessel while an end portion of the tubular member extends generally coaxially with the second vessel when the tubular member is inserted in the second vessel. The tubular member is sufficiently rigid to substantially retain the tubular member in its preformed configuration after the tubular member is expanded.

18. The method of coupling a first vessel and a second vessel in an anastomosis, the method comprising the steps of:
-
positioning a fastener comprising a tubular member longitudinally within an opening in a free end portion of the first vessel;
inserting the free end portion of the first vessel into an opening formed in a side wall of the second vessel with an end portion of the fastener extending generally longitudinally within the second vessel; and
radially expanding at least a portion of the fastener to sealingly secure the first vessel to the second vessel.

- 19. An anastomosis device for use in coupling an end of a first vessel to a side of a second vessel, the second vessel having an opening formed in a side wall thereof for insertion of the device, the device comprising a tubular member at least a portion thereof being radially expandable, the tubular member being preformed with a bend along its central longitudinal axis so that a portion of the tubular member extends out from the opening in the side wall of the second vessel while an end portion of the tubular member extends generally coaxially with the second vessel when the tubular member is inserted into the second vessel, the tubular member being sufficiently rigid in its preformed configuration to substantially retain its bent shape after the tubular member is expanded.
- 28. An anastomosis device for use in coupling a first vessel to a second vessel, the device comprising a tubular member and the first vessel attached to the tubular member, the tubular member being transformable between a compressed state in which the member has a diameter smaller than the diameter of the second vessel to permit the member to move longitudinally within the second vessel, and an expanded state in which at least a portion of the member has a diameter at least equal to the diameter of the second vessel to sealingly engage the first vessel with the second vessel.
- 34. An anastomosis device for use in coupling a first vessel to a second vessel, the device comprising a tubular member having two expandable end portions, and a central portion having a cylindrical member formed of a substantially nonporous material, the cylindrical member having an opening formed in a side wall thereof.

41. An anastomosis device for use in coupling an end of a first vessel to a side of a second vessel, the device comprising a tubular member at least a portion thereof being radially expandable, the tubular member being preformed with a bend along its central longitudinal axis and being sufficiently rigid in its preformed configuration to substantially retain its bent shape after the tubular member is expanded.
