Abstract
A device is for anchoring a suture to a bone. The device includes a suture engaged with an elastically deformable ring biased toward an unstressed state in which an outer diameter of the ring is D. The ring is compressible for insertion through a hole in a bone stabilization device having a diameter smaller than the diameter D.
Claims33
A device for anchoring a suture to a bone, comprising:
- a suture engaged with an elastically deformable ring biased toward an unstressed state in which an outer diameter of the ring is D, the ring being compressible for insertion through a hole in a bone stabilization device having a diameter smaller than the diameter D.
A kit for anchoring a suture to a bone, comprising:
- a suture;
- an elastically deformable ring biased toward an unstressed state in which an outer diameter of the ring is D, the ring being compressible for insertion through a hole in a bone stabilization device having a diameter smaller than the diameter D;
- and
- a driver sleeve extending along a first longitudinal axis and including a central channel a peripheral inner wall and two first longitudinal grooves extending into the inner peripheral wall from the central channel, the first longitudinal grooves being dimensioned to receive opposed portions of the ring in the elongated state.

A system for anchoring a suture to a bone, comprising:
- a suture engaged with an elastically deformable ring biased toward an unstressed state in which an outer diameter of the ring is D, the ring being compressible for insertion through a hole in a bone stabilization device having a diameter smaller than the diameter D;
- and
- a telescoping insertion instrument having a body extending from a proximal end to a distal end and comprising first and second coupling members extending transversely therefrom for removably coupling the ring thereto, the first and second coupling members being movable relative to one another along a longitudinal axis of the insertion instrument to move the ring between an unstressed state and a compressed state.
A method for anchoring a suture in a bone, comprising:
- inserting an elastically deformable ring non-rotatably and in a tensed state into a driver sleeve, the ring being biased toward an unstressed state in which an outer diameter of the ring is D, the ring being compressible for insertion through the driver sleeve having a diameter smaller than the diameter D;
- drawing a proximal end of a suture extending through the driver sleeve proximally to couple the ring to the driver sleeve;
- drilling a hole having a diameter d in a target portion of bone;
- inserting the ring into the hole when the ring is in a target position;
- withdrawing the driver sleeve proximally to permit the ring to expand to the unstressed state to lock the ring within the bone;
- and
- tying the suture about a target body structure to couple the target body structure to the target portion of bone.
