Abstract: The present invention relates to new surgical fasteners and methods of using the surgical fasteners. The surgical fasteners of the invention are in the form of tacks and comprise generally an elongate rod, a sharp conical head, a tail, and a transverse locking member extending from the tail above the plane of the rod. The fasteners are inserted into a bodily cavity for tissue and membrane fixation and approximation by the use of tack applicators. The tack applicators of the invention generally comprise an elongate handle, a loading tip and a carrier assembly that is removably inserted into the loading tip. The tacks are inserted and locked into the carrier assembly from which they may be disengaged.

Abstract: A compression anastomosis assembly of interlocking coupling members, particularly suitable for use in achieving anastomosis of tubular organs, having an improved locking feature to prevent inadvertent disassembly of installed coupled members. The design and configuration of the members also provide for ease in placement of the assembly in a living body wherein preferably one assembly member includes a cutting guide and a cutting ring which facilitate use of a cutting implement commonly associated with a device suitable for use during assembly implantation.

Abstract: A surgical instrument for installing a plurality of interlocking coupling members forming a compression anastomosis assembly, particularly suitable for use in achieving anastomosis of a resected tubular organ, with the instrument having a cutting portion designed and configured for rotational movement as the cutter advances to perform its intended functions of severing tissue and at least a portion of one of the members of the assembly. Also disclosed is a dual locking feature for alternately locking a driving component and an aligning component against movement where, in a first mode, the aligning component is operative when the driving component is locked and, in a second mode, the driving component is operative when the aligning component is locked. Additionally disclosed is a unique aligning component for aligning and exerting a compressive force on members of an associated coupling assembly.
