Knotless suture anchor and method of using same

A system for knotlessly anchoring a suture comprising:

• a cannula defining a center bore;
• a trocar configured for receipt in the center bore;
• a deployment shaft coupled to the cannula;
• and
• a suture anchor configured to be mounted to the trocar at a distal end of the cannula, the suture anchor including:
• a first anchor portion defining a first suture bore;
• and
• a second anchor portion defining a second suture bore;
• wherein the first anchor portion includes a first angled surface and the second anchor portion includes a second angled surface that is in contact with the first angled surface, the first and second angled surfaces extend oblique to a longitudinal axis of the suture anchor;
• wherein actuation of the deployment shaft draws the second anchor portion against the first anchor portion and proximally toward the distal end of the cannula to misalign the first suture bore and the second suture bore to enable a suture to be secured in the first suture bore and the second suture bore.

A suture anchor comprising:

• a first portion defining a first suture bore, a first deployment shaft bore, and a first center bore, the first portion having an angled distal surface that extends in a plane oblique to a longitudinal axis of the suture anchor;
• a second portion extending from a proximal end to a distal end, the second portion defining a second suture bore, a second deployment shaft bore, and a second center bore, the second portion having a proximal surface and an angled surface, the proximal surface including the deployment shaft bore and the angled surface positioned between the proximal surface and the distal end and including the second suture bore and the second center bore, wherein the angled surface is complementary to the angled distal surface of the first portion, and wherein the angled surface extends in a plane oblique to the longitudinal axis;
• wherein in a first configuration, the first portion and the second portion are aligned along the longitudinal axis of the suture anchor, and the first suture bore is aligned with the second suture bore;
• and
• wherein in a second configuration, the first portion and the second portion are offset with respect to the longitudinal axis, and the first suture bore is offset from the second suture bore to retain a suture within the first suture bore and the second suture bore.
