Abstract

A knotless tissue repair construct is disclosed herein. The construct includes a soft anchor body, with a proximal end, a distal end, and a longitudinal axis extending therebetween. The construct also includes a repair suture fixedly coupled to the anchor body. The construct also includes a transfer suture interwoven repeatedly through and along the anchor body defining a transfer path. Tension on at least one of the repair suture and transfer suture may deploy the anchor body. A transfer suture first end may transfer the repair suture through the anchor body to form a repair loop that may knotless lock the tissue repair construct.

First claim

What is claimed is:

1 . A knotless tissue repair construct comprising:
an anchor body formed of a soft material, the anchor body having a proximal end, a distal end, and a longitudinal axis; a repair suture having a first end, a second end and a cannulated length, the first end fixedly coupled to the anchor body, the cannulated length interwoven along and through a first sidewall of the anchor body and the second end extending proximally from the anchor body proximal end; and a deploying suture interwoven repeatedly through and along the anchor body and also within the cannulated length of the repair suture that is interwoven along and through the first sidewall of the anchor body; wherein tension on the deploying suture is configured to change the anchor body to a deployed configuration; and wherein while in the deployed configuration the deploying suture is configured to operatively couple to the repair suture second end and draw the repair suture second end back through the anchor body and through the cannulated length, forming a repair loop, and wherein tension on the repair suture second end is configured to knotlessly lock the repair loop.

2 . The knotless tissue repair construct of claim 1 wherein the repair suture is fixedly coupled to the anchor body with two axially overlapping knots formed by the repair suture first end, the two axially overlapping knots external to the anchor body.

3 . The knotless tissue repair construct of claim 1 wherein tension on both the repair suture second end and the deploying suture are configured to change the anchor body to the deployed configuration.

4 . The knotless tissue repair construct of claim 1 wherein the anchor body defines a tubular braided body with an inner lumen, the inner lumen having an open proximal end, and wherein the repair suture and deploying suture are both interwoven through the anchor body, and both extend directly from the open proximal end of the inner lumen.

5 . The knotless tissue repair construct of claim 1 wherein the repair suture includes a tape length segment extending from the cannulated length, the tape length segment disposed externally to the anchor body.

6 . The knotless tissue repair construct of claim 5 wherein the tape length segment defines a length that when the repair suture is formed in a repair loop, the tape length segment configured to extend around a repair tissue and back through the anchor body.

7 . The knotless tissue repair construct of claim 1 wherein the deploying suture includes a spliced loop at a first end of the deploying suture, the spliced loop configured to couple to the repair suture second end, the spliced loop having a splice length that extends through the entire anchor body and through the repair suture cannulated length.

8 . The knotless tissue repair construct of claim 7 wherein the splice length extends through the entire anchor body including the cannulated length and is operatively coupled to a tensioning actuation means of the knotless tissue repair construct, such that tensioning the deploying suture applies tension to a continuous uninterrupted length of the deploying suture splice length.

9 . The knotless tissue repair construct of claim 7 wherein the deploying suture includes a first length segment that is cannulated and a second length segment that is smaller in diameter than the first length segment and wherein the spliced loop includes the second length segment, and the splice length includes both the first and second length segment coaxially disposed.

10 . A knotless tissue repair construct comprising:
an anchor body formed of a soft material having a proximal end, a distal end, and a longitudinal axis extending therebetween, the anchor body formed with braided strands; a repair suture having a first end, a second end and a cannulated length therebetween, the first end fixed to the anchor body, the cannulated length interweaving along and through a first sidewall of the anchor body and the second end extending proximally from the anchor body proximal end; and a deploying suture interwoven repeatedly between the braided strands, through and along a second sidewall of the anchor body and also within the cannulated length of the repair suture that is interwoven along and through the first sidewall; wherein tension on the deploying suture and repair suture second end is configured to change the anchor body to a deployed configuration; wherein with the anchor body is in the deployed configuration, the deploying suture is configured to operatively couple to the repair suture second end and draw the repair suture second end back through the anchor body, and also through the cannulated length interwoven through the first sidewall, defining a knotlessly locked configuration.

11 . The knotless tissue repair construct of claim 10 wherein the repair suture includes a tape length segment extending from the cannulated length, at a location along the repair suture external to the anchor body and wherein the tape length segment defines a length configured to extend around a repair tissue and then back through the anchor body when in the knotlessly locked configuration.

12 . The knotless tissue repair construct of claim 10 wherein the deploying suture includes a spliced loop at a first end of the deploying suture, the spliced loop defining a static loop and having a splice length that extends through the anchor body and the cannulated length.

13 . The knotless tissue repair construct of claim 12 wherein the splice length extends through the anchor body and is operatively coupled to a tensioning actuation means of the knotless tissue repair construct, such that tensioning the deploying suture applies tension to a continuous uninterrupted length of the deploying member splice length.

14 . A knotless tissue repair construct comprising:
an anchor body formed of a soft material, the anchor body having a proximal end, a distal end, and a longitudinal axis; a repair suture having a first end, a second end and a cannulated length, the first end fixedly coupled to the anchor body, the cannulated length interwoven along and through a first sidewall of the anchor body and the second end extending proximally from the anchor body proximal end; and a deploying suture interwoven repeatedly through and along the anchor body and also within the cannulated length of the repair suture that is interwoven along and through the first sidewall of the anchor body, the deploying suture includes a spliced loop at a first end of the deploying suture, the spliced loop having a splice length that extends through the anchor body and through the repair suture cannulated length; wherein tension on the deploying suture is configured to change the anchor body to a deployed configuration; and wherein while in the deployed configuration the deploying suture is configured to operatively couple to the repair suture second end and draw the repair suture second end back through the anchor body and through the cannulated length, forming a repair loop, and wherein tension on the repair suture second end is configured to knotlessly lock the repair loop.

15 . The knotless tissue repair construct of claim 14 wherein the repair suture is fixedly coupled to the anchor body with two axially overlapping knots formed by the repair suture first end, the two axially overlapping knots external to the anchor body.

16 . The knotless tissue repair construct of claim 14 wherein tension on both the repair suture second end and the deploying suture are configured to change the anchor body to the deployed
