Abstract
Apparatus and methods for applying fasteners during endoscopic surgery. The apparatus generally comprises a handle portion, a triggering mechanism and a fastener applicator. One embodiment of the invention forms the fastener around a single focal point on an anvil. Another embodiment vertically stacks the fasteners in a fastener applicator which is readily detachable from the handle portion by virtue of a rotational locking system and which may be replaced with a new fastener applicator having a fresh load of vertically stacked fasteners. The various embodiments may be variously combined together in a single device. The methods generally include the following steps: forming a fastener by placing it over a single focal point anvil and pressing the fastener against the single focal point anvil using a slide.
