Abstract
Abstract A cerclage system for securing a fractured or weakened bone within a patient's body is provided. In a preferred embodiment the cerclage system includes a band formed to encircle the bone. Typically the band will be fabricated from a material having a high tensile strength such as a metal wire. A jacket supports the band in a spaced relationship from the bone. The jacket is resorbed by the patient's body.

Claim 3
Dependent Claim
18 words
An apparatus as described in claim 1 wherein said first member is tensionally stronger than said second member.
Claim 4
Dependent Claim
16 words
An apparatus as described in claim 1 wherein said first member is formed from a metal.
Claim 5
Dependent Claim
13 words
An apparatus as described in claim 3 wherein said metal is a wire.
Claim 6
Dependent Claim
21 words
An apparatus as described in claim 1 wherein said second member has a major dimension generally transverse to said first member.
Claim 7
Dependent Claim
16 words
An apparatus as described in claim 1 wherein there are a plurality of said second members.
Claim 8
Independent Claim
85 words
An apparatus for securing a fractured or weakened bone within a patient's body, comprising: a first member formed to encircle the bone, said first member having first and second ends; and a tubular second member encircling said first member, and said second member being slidable upon said first member with respect to said first member first and second ends operable for supporting said first member in a spaced relationship from the bone, wherein said second member is operable to be resorbed by a patient's body.
Claim 9
Independent Claim
85 words
An apparatus for securing a fractured or weakened bone within a patient's body, comprising: a first member formed to encircle the bone, said first member having first and second ends; and a tubular second member encircling said first member, and said second member being slidable upon said first member with respect to said first member first and second ends operable for supporting said first member in a spaced relationship from the bone, wherein said second member is operable to be resorbed by a patient's body.
Claim 10
Dependent Claim
24 words
An apparatus as described in claim 7 wherein said second member has an inner dimension large enough for multiple passes of said first member.
Claim 11
Dependent Claim
24 words
An apparatus as described in claim 7 wherein said second member has grooves to facilitate bending of said second member around a patient's bone.
Claim 12
Dependent Claim
106 words
A cerclage system for securing a fractured or weakened bone within a patient's body, comprising: a first member formed by a wire to circle the bone; a second tubular member formed from a polymeric material, the second member having a series of annular grooves to facilitate the partial encircling of the bone by said second member, said first member extending through said second member, and said second member supporting said first member in a spaced relationship from the bone, wherein said second member is operable to be resorbed by the patient's body to allow normal blood flow past said first member after the bone has healed.
Claim 13
Dependent Claim
106 words
A cerclage system for securing a fractured or weakened bone within a patient's body, comprising: a first member formed by a wire to circle the bone; a second tubular member formed from a polymeric material, the second member having a series of annular grooves to facilitate the partial encircling of the bone by said second member, said first member extending through said second member, and said second member supporting said first member in a spaced relationship from the bone, wherein said second member is operable to be resorbed by the patient's body to allow normal blood flow past said first member after the bone has healed.
Claim 14
Dependent Claim
15 words

Claim 15
Dependent Claim
25 words
A cerclage system as described in claim 10 wherein said second member has an interior dimension large enough for multiple passes of said first member.
Claim 16
Independent Claim
99 words
An apparatus for securing, a fractured or weakened bone within a patient's body, comprising: a first member formed to circle the bone, said first member having first and second ends; and a tubular second member encircling said first member, and said second member being slidable upon said first member with respect to said first member first and second ends operable for supporting said first member in a spaced relationship from the bone, said second member is operable to be resorbed by a patient's body whereby said first member is no longer securing the bone after the bone has healed.
Claim 17
Independent Claim
99 words
