Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A surgical cerclage cable comprising a multistrand fixation portion and a longitudinally attached multistrand leader portion, said fixation portion having a stiffness of from 2 to 6 millimeters of deflection per gram of force applied to a free end of a 25.4 millimeter length of the cable while the opposite end of said length is held in a fixed position, said leader portion having a stiffness of from 0.15 to 0.75 millimeters of deflection per gram of force applied to a free end of a 25.4 millimeter length of the cable while the opposite end of said length is held in a fixed position, said leader portion and said fixation portion having substantially the same diameter.
Claim 2
Dependent Claim
116 words

Claim 4
Dependent Claim
61 words
The surgical cerclage of claim 1 in which the fixation portion of the cable is made of 18 strands arranged in two concentric rings around a central core strand and the leader portion of the cable is made of six strands arranged around a central core strand, and each strand in the fixation portion and the leader portion having seven filaments.
Claim 5
Dependent Claim
22 words
The surgical cerclage cable of claim 3 in which the filaments in the leader portion and the fixation portion are stainless steel.
Claim 6
Dependent Claim
