Abstract
The present disclosure relates to an anchor assembly. The anchor assembly includes an anchor defining a cavity and an opening to the cavity; and a headless insertion member configured for arrangement within the anchor cavity, the insertion member including a body having a threaded proximal portion, a non-threaded distal portion, and a cannulation extending a partial length of the insertion member. Other anchor assemblies, anchors, and delivery devices are also disclosed.
Claims20
A method of repairing a tissue comprising:
- preparing a bone hole adjacent to the tissue;
- passing a length of suture through a through-hole of an anchor body, the anchor body defining a cavity extending from a proximal end of the anchor body, the cavity having a bottom surface spaced from a distal tip of the anchor body, the anchor body also having a plurality of wings extending from an outer surface of the anchor body, the through-hole intersecting the cavity defining first and second openings of the through-hole on opposing sides of the cavity;
- inserting the anchor body and the length of suture into the bone hole with an insertion instrument operatively coupled to the anchor body;
- adjusting a tension on the length of suture;
- and
- after inserting and adjusting, axially advancing an insertion member along the anchor body cavity towards the length of suture to secure the length of suture with the insertion member and anchor body;
- wherein the insertion member has a distal portion that defines a length having a diameter along the entire distal portion length that is smaller than a diameter of a proximal portion of the insertion member, and wherein axially advancing the insertion member comprises axially advancing the insertion member from a first position wherein the entire insertion member is proximal the through-hole, up to a second position wherein the distal portion length covers the through-hole from a point proximal of a proximal edge of the through-hole to a point distal of a distal edge of the through-hole.

A method of repairing a tissue comprising:
- preparing a bone hole adjacent to the tissue;
- drawing a length of suture through a through-hole of an anchor body the anchor body defining a threaded cavity extending from a proximal end of the anchor body, the through-hole intersecting the cavity defining first and second openings on opposing sides of the cavity;
- inserting the anchor body into the bone hole;
- adjusting a tension on the length of suture;
- and
- after drawing the length of suture through the through hole and inserting the anchor body, axially advancing an insertion member along the anchor cavity to secure the length of suture with the anchor body;
- wherein the insertion member includes a threaded proximal portion configured to threadingly engage the threaded cavity, the insertion member also including a distal portion extending distally from the threaded proximal portion that has a diameter smaller than a diameter of the threaded proximal portion, and wherein axially advancing the insertion member covers the first and second openings entirely with the distal portion.

A method of repairing a tissue comprising:
- preparing a bone hole adjacent to the tissue;
- drawing a length of suture through a through-hole of an anchor body, the through-hole intersecting a longitudinal cavity extending through the anchor body, the longitudinal cavity having a bottom surface spaced away from a distal tip of the anchor body and the through-hole defining first and second openings on opposing sides of the longitudinal cavity;
- with the length of suture drawn through the through-hole;
- inserting the anchor body into the bone hole;
- adjusting a tension on the length of suture;
- and
- once the tension is adjusted, axially advancing an insertion member into the longitudinal cavity to secure the length of suture with the anchor body;
- wherein the insertion member has a distal portion that defines a smaller diameter than a diameter of a proximal portion of the insertion member, wherein axially advancing the insertion member covers the entire through-hole with the smaller diameter distal portion from a point proximal of a proximal edge of the through-hole to a point distal of a distal edge of the through-hole.
