Abstract
Abstract A novel combination of a bone implant, e.g. a bone staple, and a tissue retention element in sliding relation therewith is disclosed. The tissue retention element is provided with a multiplicity of teeth capable of piercing and holding in place adjacent soft tissue when the implant is driven into the bone structure of a patient. Since the tissue retention element is separable from the implant, the same element can be used in combination with different bone implants.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
In combination a bone staple comprising a transverse portion and a plurality of legs integral with said transverse portion, said legs being substantially parallel, and a tissue retention element separable from said staple and comprising a base having an upper face and a lower face, means receiving said legs so that said retention element can slide upon said legs to a limiting position in which said upper face abuts said transverse portion, and a multiplicity of teeth distributed upon and extending from said lower face, said teeth being capable of piercing adjacent soft tissue when said staple is driven into the bone structure of a patient, whereby said retention element holds said soft tissue in place relative to said bone structure.
Claim 2
Dependent Claim
121 words
In combination a bone staple comprising a transverse portion and a plurality of legs integral with said transverse portion, said legs being substantially parallel, and a tissue retention element separable from said staple and comprising a base having an upper face and a lower face, means receiving said legs so that said retention element can slide upon said legs to a limiting position in which said upper face abuts said transverse portion, and a multiplicity of teeth distributed upon and extending from said lower face, said teeth being capable of piercing adjacent soft tissue when said staple is driven into the bone structure of a patient, whereby said retention element holds said soft tissue in place relative to said bone structure.
Claim 3
Dependent Claim
15 words
The combination of claim 1 wherein said legs are substantially perpendicular to said transverse portion.
Claim 4
Dependent Claim
20 words
The combination of claim 2 wherein said teeth are distributed upon said lower face in a plurality of parallel rows.
Claim 5
Dependent Claim
23 words
The combination of claim 3 wherein the teeth in adjacent parallel rows are laterally staggered when viewed in planes parallel to said rows.
Claim 6
Dependent Claim
27 words
The combination of claim 4 wherein said teeth have faces defining a series of parallel grooves oriented so as to intersect said rows in a non-perpendicular fashion.
Claim 7
Dependent Claim
15 words
The combination of claim 5 wherein the cross-sections of said parallel grooves are concave curves.
Claim 8
Dependent Claim
11 words
The combination of claim 6 wherein said cross-sections are circular arcs.
Claim 9
Dependent Claim
14 words
The combination of claim 3, 4 or 5 wherein said teeth are triangular prisms.
Claim 10
Dependent Claim
19 words
The combination of claim 1 wherein said legs are slidingly received within a plurality of openings in said base.
Claim 11
Dependent Claim
13 words
The combination of claim 1 wherein said bone staple is made of metal.
Claim 12
Dependent Claim
13 words
The combination of claim 10 wherein said retention element is made of metal.
Claim 13
Independent Claim
170 words
A method for securing soft tissue to the bone structure of a patient comprising the steps of (a) providing an assembly comprising (i) a bone implant comprising a transverse portion and a leg integral with and substantially perpendicular to said transverse portion, and (ii) a tissue retention element separable from said implant and comrising a base having an upper face and a lower face, means receiving said leg so that said retention element can slide upon said leg to a limiting position in which said upper face abuts said transverse portion, and a multiplicity of teeth distributed upon and extending from said lowr face; (b) positioning said assembly so that said leg is directed toward said bone structure and said teeth are directed toward said soft tissue; and (c) advancing said leg into said bone structure until said upper face of said base abuts said transverse portion of said implant and said teeth pierce said soft tissue, whereby said soft tissue is secured by said assembly to said bone structure.
Claim 14
Independent Claim
170 words
