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.
