Anchor apparatus

An anchor for anchoring one or more tensile members to bone, comprising:

• a housing extending along a central axis between open first and second ends, and having a hollow interior;
• a collet disposed in the hollow interior of the housing, the collet having a peripheral wall defining a central bore for accepting one or more tensile members therethrough and an exterior surface, wherein the collet is configured to be swaged around and against the one or more tensile members, wherein the collet includes an array of longitudinal grooves formed in an outer surface of the peripheral wall, each groove defining a web configured to collapse inward in response to external compressive force;
• a sleeve having a peripheral wall defining opposed interior and exterior surfaces, the sleeve disposed in the hollow interior of the housing and positioned generally axially adjacent to the collet, so as to be movable parallel to the central axis between first and second positions;
• and
• wherein at least one of the exterior surface of the collet and the interior surface of the sleeve is tapered and the sleeve and the collet are arranged such that movement of the sleeve from the first position to the second position will cause the interior surface of the sleeve to bear against the exterior surface of the collet, causing the collet to swage radially inwards around and against the one or more tensile members.
