Abstract
The present invention provides a method and end-to-side surgical anastomosis apparatus for stapling an end of a tubular tissue structure to a side of a luminal structure including an elongated housing defining a central bore extending longitudinally therethrough. The elongated housing further includes an eversion support surface extending circumferentially about the bore opening adjacent the distal end which is configured to retain and support an everted end of the received tissue structure thereon to face an intimal surface of the tissue structure in an outward direction. The anastomosis apparatus further includes an anvil having a fastener engaging surface, and a compression device having a shoulder portion formed for selectively compressing the everted end of the tissue structure and a surface of the luminal structure together against the fastener engaging surface. The compression device is further formed to deform the fasteners into contact with the everted end of the tubular tissue structure and the luminal structure to create an anastomotic bond between the tubular tissue structure and the luminal structure. At least one driver pin is preferably provided moveable relative to …
