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.
