An improvement in a stapling device and method designed to capture a tissue fold between first and second members in the device and to staple and cut the fold to form a stapled tissue plication with a hole therein is disclosed. The improvement includes an engagement assembly (252) in the first member movable from a re-tracted position in the first member to an extended posi-tion in the second member, and releasably attached to second member, an anchor assembly that includes the an-chor (220), wherein (i) movement of the engagement as-sembly (252) from its retracted to its extended position, through a tissue fold captured in the device between the first and second device members, is operable to engage the anchor (220), and (ii) movement of the engagement assembly, with the anchor (220) engaged therewith, back toward its retracted position, is effective to pull at least a portion of the anchor (220) through the hole in the sta-pled tissue plication formed by the device. |
