A method and apparatus (10) for attaching a tubular graft (20) to a body structure (332) is disclosed. The apparatus (10) includes a central rod (12) with an anvil (14) attached at a distal end (16) thereof. Driver pins (24) move distally to eject staples (210) which are housed in a cartridge (26). The staple cartridge (26) has an outer circumference sufficient to accommodate everted end (34) of tubular graft (20), and an inner diameter sufficient to accommodate a majority of the tubular graft (2) therein. Accordingly, the method includes positioning the rod (12) in the graft (20), everting an end (34) of the graft around a shoulder (36) of the staple cartridge (26), inserting the anvil (14) through an opening (334) in the body structure (332), compressing the graft (20) and the body structure (332) between the anvil (14) and shoulder (36), and moving the driver pins (24) distally to engage and drive the staples (210), thus stapling the graft (20) to the body structure (332). |
