Abstract
Abstract A cable winding for retention of bone in surgery having a crimp for retaining the cables together. The crimp has a bore of oval cross section, with its exterior being preferably oval in cross section as well. The cable sections extend through the single bore in side-by-side relation. Outwardly projecting flanges extend from the crimp ends for at least about 120° about the periphery to create a space between the flanges when the flanges rest on bone. This space may be used to receive the crimping jaws during the crimping process so that the crimp does not have to be forced outwardly from the bone during the crimping process. Thus, a more consistent, predetermined tension can be provided to the cable on crimping.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
110 words
A malleable metal, tubular crimp for securing a plurality of cable portions together, said crimp defining a bore of generally oval cross-section extending entirely through said crimp to permit a plurality of said cable portions to extend therethrough in side-by-side relation, said crimp having a pair of opposed ends which each define an outwardly projecting flange extending at least about 120° but only partially about opposed ends of said crimp, said flanges extending outwardly from said crimp by a distance of at least about 0.02 inch, whereby said flanges may rest against a bone while providing spacing for crimping jaws between a central portion of said crimp and said bone.
Claim 2
Dependent Claim
110 words
A malleable metal, tubular crimp for securing a plurality of cable portions together, said crimp defining a bore of generally oval cross-section extending entirely through said crimp to permit a plurality of said cable portions to extend therethrough in side-by-side relation, said crimp having a pair of opposed ends which each define an outwardly projecting flange extending at least about 120° but only partially about opposed ends of said crimp, said flanges extending outwardly from said crimp by a distance of at least about 0.02 inch, whereby said flanges may rest against a bone while providing spacing for crimping jaws between a central portion of said crimp and said bone.
Claim 3
Dependent Claim
29 words
The crimp of claim 1 in which said generally oval bore defines major and minor cross-sectional axes, said major axis being in generally longitudinal relation with said first side.
Claim 4
Dependent Claim
24 words
The crimp of claim 1 in which said crimp flanges extend in an arc angle of about 180° to 270° about said crimp ends.
Claim 5
Dependent Claim
20 words
The crimp of claim 1 which has an outer surface between said flanges that is generally oval in cross section.
Claim 6
Dependent Claim
24 words
The crimp of claim 1 in which said crimp flanges extend in an arc angle of about 200° to 250° about said crimp ends.
Claim 7
Dependent Claim
173 words
In combination, a cable winding, a crimp, and crimping pliers, said cable winding being adapted to be placed about a bone, said cable winding having first cable portions which extend through a single bore of said crimp, said bore being of generally oval cross-section and extending entirely through said crimp with said cable portions extending through said bore in side-by-side relation, said crimp having a pair of opposed ends which each define an outwardly projecting flange about opposed ends of a first side of said crimp, said flanges being adapted to be in contact with said bone to cause a space to be created between most of said first side and said bone; said crimp being carried in jaws of said crimping pliers, a portion of at least one of said jaws extending into said space while the flanges are in contact with said bone, to permit said crimp to be crushed by the crimping pliers to secure said cable portions within said crimp while the flanges remain in contact with said bone.
Claim 8
Dependent Claim
173 words
In combination, a cable winding, a crimp, and crimping pliers, said cable winding being adapted to be placed about a bone, said cable winding having first cable portions which extend through a single bore of said crimp, said bore being of generally oval cross-section and extending entirely through said crimp with said cable portions extending through said bore in side-by-side relation, said crimp having a pair of opposed ends which each define an outwardly projecting flange about opposed ends of a first side of said crimp, said flanges being adapted to be in contact with said bone to cause a space to be created between most of said first side and said bone; said crimp being carried in jaws of said crimping pliers, a portion of at least one of said jaws extending into said space while the flanges are in contact with said bone, to permit said crimp to be crushed by the crimping pliers to secure said cable portions within said crimp while the flanges remain in contact with said bone.
Claim 9
Dependent Claim
30 words
The crimp of claim 6 in which said generally oval bore defines major and minor cross-sectional axes, said major axis being in generally in longitudinal relation with said first side.
Claim 10
Dependent Claim
19 words
The crimp of claim 7 in which said crimp flanges extend about 120° to 270° about said crimp ends.
Claim 11
Dependent Claim
20 words
The crimp of claim 8 which has an outer surface between said flanges that is generally oval in cross section.
Claim 12
Dependent Claim
129 words
A malleable metal, tubular crimp for securing a plurality of cable portions together, said crimp defining a bore of generally oval cross-section extending entirely through said crimp to permit a plurality of said cable portions to extend therethrough in side-by-side relation, said crimp having a pair of opposed ends which each define an outwardly projecting flange extending in an arc angle of about 180° to 250° about opposed ends of a first side of said crimp, in which said generally oval bore defines major and minor cross-sectional axes, said major axis being in generally longitudinal relation with said first side, whereby said crimp flanges may rest against a bone to provide spacing for crimping jaws between a central portion of the first side of said crimp and said bone.
