Abstract
A tacker instrument for laparoscopic applications fits within a cannula and incorporates within a sleeve a positioning and driving system coupled to a tack holder mechanism at the distal end. The tack is held unexposed during entry but then may be extended to a predetermined position for embedment, with position being verifiable through the sleeve. Impact forces for embedding or removing the tack are applied to the positioning and driving mechanism, and the tack and tack holder are configured so that there is lateral disengagement or engagement of the two. In one version the mechanism is linear, while in a second version the distal end of the sleeve device can be angulated for perpendicular tack entry or removal with impelling forces being applied through a flexible shaft segment.
