Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 89 words
A removable implant, comprising an implant body; at least one flexible, thin wire-shaped structure having a portion slidably wrapped at least once about the implant body; and a catch device provided on an end of the structure, said slidable portion of the structure configured to shorten as the catch device is pulled in the longitudinal direction; wherein the implant body is reducible in diameter, at least partially by pulling the catch device in a longitudinal direction and shortening the slidable portion of the structure wrapped about the implant body.
Claim 2
Dependent Claim 89 words
A removable implant, comprising an implant body; at least one flexible, thin wire-shaped structure having a portion slidably wrapped at least once about the implant body; and a catch device provided on an end of the structure, said slidable portion of the structure configured to shorten as the catch device is pulled in the longitudinal direction; wherein the implant body is reducible in diameter, at least partially by pulling the catch device in a longitudinal direction and shortening the slidable portion of the structure wrapped about the implant body.
Claim 3
Dependent Claim 22 words
The implant of claim 1 , wherein the slidable portion of the structure is wrapped more than once about the implant body.
