Abstract
Abstract A cerclage wire passer comprises a proximal portion with handle structure and an S-shaped distal portion with an eyelet hole at the outer end thereof. The S-shaped distal portion includes a primary curved segment that fits around the bone to be cerclaged and a secondary reverse curved segment which accommodates the mass of tissue and muscle surrounding the bone when the wire passer is manipulated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
80 words
A cerclage wire passer for encircling a femur bone with orthopedic wire comprising a proximal portion with handle means and an S-shaped distal portion with an eyelet hole at the outer end thereof, the S-shaped distal portion including a primary curved segment constructed and arranged to fit around the femur bone being cerclaged and a secondary reverse curved segment positioned between the proximal portion and the primary curved segment constructed and arranged to accommodate the quadriceps mass surrounding the bone.
Claim 2
Dependent Claim
80 words
A cerclage wire passer for encircling a femur bone with orthopedic wire comprising a proximal portion with handle means and an S-shaped distal portion with an eyelet hole at the outer end thereof, the S-shaped distal portion including a primary curved segment constructed and arranged to fit around the femur bone being cerclaged and a secondary reverse curved segment positioned between the proximal portion and the primary curved segment constructed and arranged to accommodate the quadriceps mass surrounding the bone.
Claim 3
Dependent Claim
24 words
A cerclage wire passer as in claim 1 wherein the primary curved segment and the secondary reverse curved segment are in the same plane.
Claim 4
Dependent Claim
39 words
A cerclage wire passer as in claim 2 wherein the eyelet hole at the outer end of the S-shaped distal portion is arranged substantially normal to the plane of the primary curved segment and the secondary reverse curved segment.
Claim 5
Dependent Claim
32 words
A cerclage wire passer as in claim 2 wherein the handle means defines a plane arranged substantially normal to the plane of the primary curved segment and the secondary reverse curved segment.
Claim 6
Dependent Claim
33 words
A cerclage wire passer as in claim 1 wherein the primary curved segment has a radius of approximately 7/8 inch and the secondary reverse curved segment has a radius of approximately 15/8 inch.
Claim 7
Dependent Claim
33 words
A cerclage wire passer as in claim 1 wherein the primary curved segment has a radius of approximately 11/8 inch and the secondary reverse curved segment has a radius of approximately 15/8 inch.
Claim 8
Dependent Claim
35 words
A cerclage wire passer as in claim 1 wherein the secondary reverse curved segment of the S-shaped distal portion is connected to the proximal portion at an angle in the range of 90° to 180°.
Claim 9
Dependent Claim
47 words
A cerclage wire passer as in claim 7 wherein the secondary reverse curved segment of the S-shaped distal portion is connected to the proximal portion at an angle of about 180° whereby the secondary reverse curved segment initially forms a straight line extension of the proximal portion.
Claim 10
Dependent Claim
31 words
A cerclage wire passer as in claim 7 wherein the secondary reverse curved segment of the S-shaped distal portion is connected to the proximal portion at an angle of about 125°.
Claim 11
Dependent Claim
