Abstract
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.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
54 words
An implantable apparatus for wedging within an opening formed within a bone comprising a body having a longitudinal cross-section defined by a perimeter, said cross-section being a quadrilateral shape and, said perimeter forming at least one biting edge, said body further defining a hole through said body in a direction transverse to said cross-section.
Claim 2
Dependent Claim
54 words
An implantable apparatus for wedging within an opening formed within a bone comprising a body having a longitudinal cross-section defined by a perimeter, said cross-section being a quadrilateral shape and, said perimeter forming at least one biting edge, said body further defining a hole through said body in a direction transverse to said cross-section.
Claim 3
Dependent Claim
17 words
The apparatus according to claim 1 wherein said body perimeter is in the shape of a trapezoid.
Claim 4
Dependent Claim
17 words
The apparatus according to claim 1 wherein said body perimeter is in the shape of a parallelogram.
Claim 5
Dependent Claim
27 words
The apparatus according to claim 1 wherein the perimeter is defined by four sides and two of the sides diverge in a direction away from said hole.
Claim 6
Dependent Claim

Claim 9
Dependent Claim
15 words
The apparatus according to claim 7 wherein at least one of said sides is rounded.
Claim 10
Dependent Claim
22 words
The apparatus according to claim 1 wherein said hole is nearer to one side than it is to a noncontiguous second side.
Claim 11
Dependent Claim
16 words
The apparatus according to claim 1 wherein said biting edge forms at least one engaging tooth.
Claim 12
Dependent Claim
16 words
The apparatus according to claim 10 wherein said biting edge forms a plurality of biting teeth.
Claim 13
Dependent Claim
14 words
The apparatus according to claim 1 wherein said hole has received therein a suture.
Claim 14
Dependent Claim
19 words
The apparatus according to claim 12 wherein said suture has at least two free ends extending from said body.
Claim 15
Dependent Claim
18 words
The apparatus according to claim 1 wherein the apparatus is presented in a sterile condition prior to use.
Claim 16
Dependent Claim
16 words
The apparatus according to claim 1 wherein said perimeter is formed of three mutually adjacent sides.
Claim 17
Dependent Claim
17 words
The apparatus according to claim 1 further including a thin longitudinal stem portion extending from said body.
Claim 18
Dependent Claim
21 words
The apparatus according to claim 16 wherein said stem is integral with and formed of the same material as said body.
Claim 19
Dependent Claim
25 words
The apparatus according to claim 16 wherein said body is of a medical grade material and said stem is of a different medical grade material.
Claim 20
Dependent Claim
18 words
The apparatus according to claim 16 wherein said stem is connected to said body by a frangible portion.
Claim 21
Dependent Claim
22 words
The apparatus according to claim 19 wherein said frangible portion is formed of at least two intersecting web portions forming a cross.
Claim 22
Dependent Claim
22 words
The apparatus according to claim 16 further including a protrusion on said stem for positioning of said stem within an implantation apparatus.
Claim 23
Dependent Claim
26 words
The apparatus according to claim 16 wherein said body is made of a medical grade metal material and said stem is made of a bioabsorbable polymer.
Claim 24
Dependent Claim
16 words
The apparatus according to claim 1 wherein the body material is made of a bioabsorbable material.
Claim 25
Dependent Claim
15 words
The apparatus according to claim 1 wherein the body material is of a biocompatible metal.
Claim 26
Dependent Claim
16 words
The apparatus according to claim 1 wherein said body is made of a medical grade polymer.
Claim 27
Dependent Claim
64 words
The apparatus according to claim 1 wherein an inserter is attached to said body and said inserter has an upper portion and a lower portion and said upper portion is of a diameter larger than a diameter of said lower portion and a transition zone extends between said upper portion and lower portion for positioning said body within an opening during an implantation procedure.
Claim 28
Dependent Claim
38 words
The apparatus according to claim 26 wherein said inserter further defines at least one longitudinally extending slot in the upper portion at about the transition zone for passage of a suture to prevent damage during the insertion process.
