Abstract
Abstract A system for inserting a cannulated tissue anchor during endoscopic surgical procedures. The system incorporates an elongated generally cylindrical tissue anchor having a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The head is elongated along a major axis which is misaligned relative to the rows of barbs on the body of the tissue anchor in order to enhance retention of the anchor within selected tissue. The anchor may be inserted during an endoscopic surgical procedure by a single-handed operation utilizing an instrument having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle. The system incorporates a package/loading device to facilitate the assembly of a cannulated tissue anchor with the inserter, the package/loading device being provided with a means for guiding the inserter needle through the axial bore of the tissue anchor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
A tissue anchor device comprising: an elongated shaft having an axis, a proximal end, a distal end and a longitudinally extending bore therethrough; a plurality of barbs longitudinally spaced along said shaft, said barbs arranged in four linear rows each row spaced 90° about said shaft from an adjacent row, said barbs being tapered in a distal direction to facilitate distal movement of said shaft through material, the barbs of two diametrically opposed rows having proximally facing surfaces which are aligned perpendicular to said bore and the barbs of the remaining two diametrically opposed rows having proximally facing surfaces which are undercut.
Claim 2
Dependent Claim
102 words
A tissue anchor device comprising: an elongated shaft having an axis, a proximal end, a distal end and a longitudinally extending bore therethrough; a plurality of barbs longitudinally spaced along said shaft, said barbs arranged in four linear rows each row spaced 90° about said shaft from an adjacent row, said barbs being tapered in a distal direction to facilitate distal movement of said shaft through material, the barbs of two diametrically opposed rows having proximally facing surfaces which are aligned perpendicular to said bore and the barbs of the remaining two diametrically opposed rows having proximally facing surfaces which are undercut.
Claim 3
Dependent Claim
60 words
A tissue anchor device according to claim 1 further comprising: a transversely extending head situated at the proximal end of said shaft, said head having an aperture aligned with said bore and said head being generally elongated along a major axis which, when viewed along said axis of said device, is misaligned relative to at least one of said barbs.
Claim 4
Dependent Claim
116 words
A tissue anchor device comprising: an elongated shaft having an axis, a proximal end, a distal end and a longitudinally extending bore therethrough; a plurality of barbs longitudinally spaced along said shaft, said barbs being tapered in a distal direction to facilitate distal movement of said shaft through material, said barbs aligned in at least one longitudinally extending row on the external surface of said shaft; said barbs arranged in at least two longitudinally aligned rows which are spaced a predetermined arcuate distance from each other at each point along the length of said shaft, said barbs of one of said rows being longitudinally spaced from the associated barbs of an adjacent row of said barbs.
Claim 5
Dependent Claim
116 words
A tissue anchor device comprising: an elongated shaft having an axis, a proximal end, a distal end and a longitudinally extending bore therethrough; a plurality of barbs longitudinally spaced along said shaft, said barbs being tapered in a distal direction to facilitate distal movement of said shaft through material, said barbs aligned in at least one longitudinally extending row on the external surface of said shaft; said barbs arranged in at least two longitudinally aligned rows which are spaced a predetermined arcuate distance from each other at each point along the length of said shaft, said barbs of one of said rows being longitudinally spaced from the associated barbs of an adjacent row of said barbs.
Claim 6
Dependent Claim
60 words
A tissue anchor device according to claim 2 further comprising: a transversely extending head situated at the proximal end of said shaft, said head having an aperture aligned with said bore and said head being generally elongated along a major axis which, when viewed along said axis of said device, is misaligned relative to at least one of said barbs.
