International Classification:

A61B 1704

US Classification:

606232

Abstract:

A suture anchor is described which in one form may be easily fabricated from extruded material by angular cuts and bore holes which provide an offset pulling force to the suture. In an alternate and preferred embodiment the suture anchor is injection molded having an annular displaced corner and abutment wall which act to seat the suture anchor firmly within a bore hole. Novel application means are also disclosed which hold the suture anchor on a frangible shaft for insertion and upon completion of the insertion permit fracture of the frangible portion and removal of the instrument. In another form of the invention, the suture anchor comprises a substantially wedge-shaped body having a smaller distal end and a larger proximal end, means thereon for retaining a suture, and means thereon for releasable connection to an inserter shaft; a boundary surface and a plow surface of the body intersecting to form a biting edge at the proximal end of the body; and the boundary surface and an abutment surface of the body intersecting to form a cam surface at the proximal end of the body; and the biting edge being adapted to be in engagement with a first wall portion of a bore in a bone and the cam surface being adapted to be in engagement with a second wall portion of the bore opposed to the first wall portion; wherein tension on the inserter shaft is operable to move the cam portion along the bore second wall portion and rotate the body in the bore such that the biting edge bites into the bore first wall portion to lock the body in the bore.

International Classification:

US Classification:

606220

Abstract:

A method of tissue compression is disclosed herein where the device to cause such compression is composed of a fastener bar and receiver. The device has the capability to self-adjust to tissues of varying thicknesses to cause hemostasis. This tissue gap variability allows for compression of regions of tissue where thick and thin tissue are both present. This variability also enables the same device to be used on a wide variety of tissues of different thicknesses. The tissue fastener bar of this invention contains a series of cut-out portions which distribute the compressive forces along the device in an alternating, staggered manner. The receiver is of a generally U-shaped configuration with the fastener bar being contained at least partially within the U-shape. Compression occurs between the side walls of the receiver and the fastener bar and variability in gap is accomplished by flexure of the side walls of the receiver. Varying side wall flexure is enhanced by cut-out portions in the receiver which allow each segment to flex somewhat independently.
