Knotless all suture tissue repair
First Claim
1. An anchor for securing a tissue to a bone or tissue to tissue in a human or animal without tying a knot, the anchor comprising:
- an anchoring implant for inserting into the bone or the tissue, the anchoring implant comprising a first configuration having an elongate body, a longitudinal axis, distal and proximal ends, and sidewalls; and
a suture extending through the anchoring implant and comprising an elongate first suture-locking tunnel that extends along the implant sidewalls;
wherein the suture has a first length portion extending from the anchoring implant for making a first loop through the tissue, returning to the anchoring implant, and drawing through the first suture-locking tunnel;
wherein applying a first force in a proximal direction to a portion of the suture causes the first suture-locking tunnel to radially decrease thereby locking the suture and prohibiting the first loop from expanding; and
wherein applying tension to at least one end of the suture when the anchoring implant is located in the bone or the tissue causes the anchoring implant to change from the first configuration into a second configuration comprising an axially shortened, and radially extended shape so as to deploy the anchoring implant in a hole;
wherein the anchor further comprises a means of maintaining the suture locking tunnel in alignment relative to the anchoring implant comprising a second length portion of the suture distinct from the first suture locking tunnel that is both wrapped around an outer circumference of the distal end of the anchoring implant and also fed back through itself for a predetermined length at the anchoring implant distal end.

Abstract
A knotless tissue repair assembly for attachment of tissue to bone includes an anchoring implant with a length of suture threaded therethrough. The implant is preferably a soft flexible three-dimensional structure. The implant may be actuated from a first elongate low profile shape into a second short radially expanded shape having a larger diameter than the hole through which it was placed. The suture extends through the anchor, through a tissue to be secured, and back through a designated suture-binding region or passageway within the anchor enabling the suture to be secured therein and without the need for a physician to tie a knot. Further tension applied to a suture leg approximates the tissue to the anchor until a desired tension or distance between the tissue and anchor is achieved.

11. An anchor for securing a tissue to a bone or tissue to tissue in a human or animal without tying a knot, the anchor comprising:
-
an anchoring implant for inserting into the bone or the tissue, the anchoring implant having an elongate body, a longitudinal axis and distal and proximal ends; and a suture extending through the anchoring implant and comprising an elongate first suture-locking tunnel interwoven with the anchoring implant; wherein the suture has a first length portion extending from the anchoring implant for making a first loop through the tissue, returning to the anchoring implant, and drawing through the suture-locking tunnel and wherein the suture further defines a means of maintaining the suture-locking tunnel in alignment relative to the anchoring implant comprising a second loop of the suture that is both wrapped about the distal end of the anchoring implant and also fed back through itself at the anchoring implant distal end for a predetermined length; wherein applying a first tension in a proximal direction to a first suture end causes the suture-locking tunnel to radially decrease thereby locking the suture and prohibiting the first loop from expanding; and wherein applying tension to either or both the first suture end or a second suture end when the anchoring implant is located in the bone or tissue causes the anchoring implant to deploy. - View Dependent Claims (12, 13, 14, 15, 16)
