<p>The apparatus generally comprises a handle portion (10), a triggering mechanism (30) and a fastener applicator (20). One embodiment of the invention forms the fastener around a single focal point on an anvil (130). Another embodiment vertically stacks the fasteners (80) in a fastener applicator (40) which is readily detachable from the handle portion (10) 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 (80). A third embodiment of the invention has a fastener applicator having only one actuated part in its application mechanism, and makes use of biased springs controlled by position of the actuated part for the remaining part of the mechanism. A fourth embodiment of the invention deploys a plunger/ratchet assembly (408) and pawl (400) within the handle portion (10) of the apparatus to ensure that the apparatus application mechanism will not reverse in the middle of a triggered application stroke. The various embodiments may be variously combined together in a single device.</p> |
