Abstract
Systems, apparatuses and methods for securing tissue to bone using a bone anchoring system are described. Methods and apparatuses may allow transformation between locked and unlocked states, thereby allowing adjustment of the tension in the suture. The apparatus and/or methods may allow unidirectional movement of a suture, while preventing slippage or movement of the suture and tissue in the opposite direction. Ends of a suture may be individually tensioned to adjust positioning of a tissue with respect to a bone.
Claims17
A method comprising:
- releasably attaching a bone anchor to a distal end of a loading portion;
- removably coupling at least a first portion of an anchor holder to the distal end of the loading portion;
- removably coupling a second portion of the anchor holder to the first portion, wherein the first and second portions are separable halves of the anchor holder;
- threading a suture through the bone anchor and the anchor holder;
- and
- removing the anchor holder from the distal end of the loading portion.

A method comprising:
- releasably attaching a bone anchor to a distal end of a loading portion, wherein releasably attaching comprises retaining the bone anchor to the loading portion with a tether;
- removably coupling at least a first portion of an anchor holder to the distal end of the loading portion;
- removably coupling a second portion of the anchor holder to the first portion;
- threading a suture through the bone anchor and the anchor holder;
- and
- removing the anchor holder from the distal end of the loading portion.

4 more elements
A method comprising:
- releasably attaching a bone anchor to a distal end of a loading portion;
- removably coupling an anchor holder with a cavity to the distal end of the loading portion and the bone anchor;
- threading a suture through the bone anchor and the anchor holder, wherein threading the suture comprises threading the suture through a two bar locking mechanism of the bone anchor;
- uncoupling the anchor holder from the loading portion while the distal end of the loading portion and the bone anchor are within the cavity;
- and
- removing the anchor holder from the distal end of the loading portion.
3 more elements
A method comprising:
- releasably attaching a bone anchor to a distal end of a loading portion;
- removably coupling at least a first portion of an anchor holder to the distal end of the loading portion, wherein the first portion defines a first inner surface of a cavity, wherein the first inner surface is on one side of the bone anchor;
- removably coupling a second portion of the anchor holder to the first portion, wherein the second portion defines a second inner surface of the cavity, wherein the second inner surface is on another side of the bone anchor;
- threading a suture through the bone anchor and the anchor holder, wherein threading the suture comprises threading the suture through a two bar locking mechanism of the bone anchor;
- and
- removing the anchor holder from the distal end of the loading portion.
