Soft tissue repair system
First Claim
1. A suture anchor assembly comprising:
- an anchor having a first passageway extending through at least a portion of the anchor;
a suture comprising a proximal end and an opposing distal end, a portion of the suture between the proximal end and the distal end being formed into a loop, the loop being at least partially passed through the first passageway, at least one of the proximal end or the distal end of the suture being passed through the loop such that pulling on at least one of the proximal end or the distal end of the suture that is passed through the loop causes the suture to selectively lock against the anchor; and
a retraction line threaded through the loop of the suture such that the application of tension by the retraction line on the loop causes the suture to selectively unlock from the anchor.

Abstract
A suture anchor delivery system includes a handle having a needle extending therefrom. A suture anchor assembly is slidably received on the needle. The suture anchor assembly includes a proximal anchor, a distal anchor, and a suture extending therebetween. The suture is secured to the proximal anchor by forming a loop in the suture and passing the loop at least partially through a passageway in the proximal anchor. One end of the suture is then secured to the distal anchor. The other end of the suture is passed through the loop and terminates in a free end to selectively lock the suture against the proximal anchor. A retraction line is passed through the loop to allow a surgeon to selectively adjust the length of the suture between the two anchors and/or to selectively unlock the suture from the proximal anchor.

6. A suture anchor assembly comprising:
-
an anchor having a first passageway and a spaced apart second passageway each extending through at least a portion of the anchor;
a suture comprising a proximal end and an opposing distal end, a portion of the suture between the proximal end and the distal end passing through the first passageway and the second passageway so as to form a loop, at least one of the proximal end or the distal end of the suture being passed through the loop such that pulling on at least one of the proximal end or distal end of the suture that is passed through the loop causes the suture to selectively lock against the anchor; and
a retraction line threaded through the loop of the suture such that the application of tension by the retraction line on the loop causes the suture to selectively unlock from the anchor. - View Dependent Claims (7, 8, 9)

10. A suture anchor assembly comprising:
-
an anchor comprising;
a top surface and an opposing bottom surface;
an elongated channel recessed into the bottom surface; and
a first passageway and a spaced apart second passageway extending from the top surface to the channel;
a suture comprising a proximal end and an opposing distal end, a portion of the suture between the proximal end and the distal end being formed into a loop, the loop being at least partially passed through the first passageway, at least one of the proximal end or the distal end of the suture being passed through the second passageway and then through the loop such that pulling on the proximal end or the distal end of the suture that is passed through the loop causes the suture to selectively lock against the anchor. - View Dependent Claims (11, 12, 13, 14)

36. A method for securing a suture on an anchor wherein a suture comprises a proximal end and an opposing distal end, a portion of the suture between the proximal end and the distal end being formed into a loop, the loop being passed at least partially through a passageway formed on the anchor, at least one of the proximal end or the distal end of the suture being passed through the loop, the method comprising:
-
while holding securely the proximal end or the distal end of the suture that is passed through the loop, pulling on a retention line passing through the loop of the suture so as to remove any unwanted slack from the suture distal of the loop by enlarging the loop; and
pulling on the proximal end or distal end of the suture that is passed through the loop so as to remove slack from the loop and selectively lock the suture to the anchor. - View Dependent Claims (37, 38)

placing a first anchor into soft tissue, a suture being connected to the first anchor;
placing a second anchor into soft tissue at a distance from the first anchor, the suture passing through at least a portion of the second anchor and terminating at a free end; and
pulling on a retraction line extending through a loop formed on the suture so as to decrease the length of suture between the first anchor and the second anchor. - View Dependent Claims (40, 41)
