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 retracted position in the first member to an extended position in the second member, and releasably attached to second member, an anchor assembly that includes the anchor (220), wherein (i) movement of the engagement assembly (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 stapled tissue plication formed by the device.

L'invention porte sur une amélioration apportée à un dispositif d'agrafage et sur un procédé conçu pour capturer un pli de tissu entre des premier et second éléments dans le dispositif et pour agrafer et découper le pli pour former une plicature de tissu agrafée avec un trou dans celle-ci. L'amélioration comprend un ensemble d'engagement (252) dans le premier élément mobile d'une position rétractée dans le premier élément à une position étendue dans le second élément, et fixée de façon amovible au second élément, un ensemble ancre qui comprend l'ancre (220), (i) un mouvement de l'ensemble d'engagement (252) de sa position rétractée à sa position étendue, par un pli de tissu capturé dans le dispositif entre les premier et second éléments du dispositif, étant actionnable pour engager l'ancre (220), et (ii) un mouvement de l'ensemble d'engagement, avec l'ancre (220) engagée avec celui-ci, à nouveau vers sa position rétractée, étant efficace pour tirer au moins une partie de l'ancre (220) à travers le trou dans la plicature de tissu agrafée formée par le dispositif.
