A device for placing a surgical fastener, including an elongated shaft having a distal and proximal end and an interior surface extending longitudinally therein. The elongated shaft has at least a pair of channels extending longitudinally therein. The device includes at least one fastener located within the elongated shaft and in contact with the surface and a pushing mechanism. The fastener having a pair of bosses extending laterally therefrom, wherein each of the bosses resides in one of the pair of channels. The pushing mechanism moves proximally and distally within the elongated shaft. The device further includes a member within the elongated shaft cooperating with the pushing mechanism for moving the bosses away from each other as the fastener is advanced distally so as to close the fastener.

Dispositif servant à mettre une attache chirurgicale en place, comprenant une tige allongée ayant une extrémité distale, une extrémité proximale et une surface intérieure qui s'étend longitudinalement. La tige allongée comporte au moins une paire de canaux s'étendant longitudinalement à l'intérieur de la tige. Le dispositif comprend au moins une attache située à l'intérieur de la tige allongée, en contact avec la surface et un mécanisme de poussée. L'attache comporte une paire de bossages qui s'étendent latéralement par rapport à l'attache. Chacun des bossages est logé dans un des deux canaux. Le mécanisme de poussée se déplace de façon proximale et distale à l'intérieur de la tige allongée. Le dispositif comprend en outre un élément dans la tige allongée qui, avec le mécanisme de poussée, écarte les bossages l'un de l'autre pendant que l'attache est poussée en direction distale, de façon à fermer celle-ci.
