Device for applying a tissue fastener having a shaft with a reduced cross-section

摘要

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. <IMAGE>
