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.

First claim

We claim:

1. A tissue repair assembly comprising:
a soft anchor defining an elongate body having a proximal end, a distal end, longitudinal axis therebetween and a maximum width extending from a first external side surface to a second external side surface;
a suture interwoven repeatedly through the soft anchor, with a first and second suture tails extending from the soft anchor proximal end,
a first and a second suture snares extending within a length of the suture, defining a suture locking passage along the length of the suture;
wherein the first and second snares both extend around the first and second external side surfaces and are configured to operatively couple to the first and second suture tails respectively and draw the first and second suture tails around the soft anchor and through the suture locking passage to form two closed suture loops, each of the two closed suture loops crossing over each other within the suture locking passage and emerging at opposite ends of the suture locking passage to each other, such that the two suture tails extend from the suture locking passage in a proximal direction away from the soft anchor proximal end.

2. The tissue repair assembly of claim 1 wherein tensioning at least one of the suture tails causes the soft anchor to change from a first configuration, in which the soft anchor is elongate, to a second configuration, in which the soft anchor maximum width is increased.

3. The tissue repair assembly of claim 2 wherein tensioning at least one of the suture tails causes the suture locking passage to knotlessly lock the suture.

4. The tissue repair assembly of claim 1 wherein tensioning at least one of the suture tails deploys the soft anchor and knotlessly locks the assembly.

5. The tissue repair assembly of claim 1 wherein the suture locking passage extends across the soft anchor longitudinal axis at the soft anchor distal end.

6. The tissue repair assembly of claim 1 wherein the soft anchor defines a lumen having a diameter, the maximum width including a single lumen diameter.

7. The tissue repair assembly of claim 6 wherein the first snare is configured to draw the first suture tail from the first external side surface through the suture locking passage.

8. The tissue repair assembly of claim 6 wherein the second snare is configured to draw the second suture tail from the second external side surface, opposite the first external surface through the suture locking passage.

9. The tissue repair assembly of claim 1 wherein the suture locking passage extends perpendicularly to the anchor longitudinal axis.

10. A tissue repair assembly comprising:
a soft anchor having a proximal end, a distal end, a tubular sidewall and a longitudinal axis extending therebetween, the tubular sidewall defining a first external side surface and a second external side surface, the first and second external side surfaces on opposing sides of the soft anchor longitudinal axis;
a suture threaded repeatedly through both the first and second external side surfaces, having a first and a second suture tails extending from the soft anchor proximal end;
a first snare extending along the soft anchor and through a first suture locking passage of the suture;
wherein the first snare is configured to operatively couple to the first suture tail and draw the first suture tail along the soft anchor and through the first suture locking passage to form a first closed adjustable suture loop.

11. The tissue repair assembly of claim 10 further comprising a second snare extending along the soft anchor and through a second suture locking passage; the first and second suture locking passage extending parallel to each other, wherein the second snare is configured to operatively couple to the second suture tail and draw the second suture tail along the soft anchor and through a second suture locking passage to form a second closed adjustable suture loop.

12. The tissue repair assembly of claim 11 wherein the first snare is configured to draw the first suture tail along the first external side surface and then through the first suture locking passage wherein the second snare is configured to draw the second suture tail along the second external side surface and then through the second suture locking passage and crosses over the first suture tail.

13. The tissue repair assembly of claim 11 wherein both the first and second snares each include a loop end configured to snare a suture tail, the first snare loop end extending directly from the proximal end of the soft anchor at the first external surface and the second snare loop end extending directly from the proximal end of the soft anchor at the second external side surface.

14. The tissue repair assembly of claim 11 wherein the first and second suture locking passages extend perpendicularly to the soft anchor longitudinal axis at a soft anchor distal end.

15. The tissue repair assembly of claim 11 wherein the second snare is configured to draw the second suture tail around the first and second external surfaces of the soft anchor and through the second suture locking passage, in an opposite direction around the soft anchor to the first snare.

16. The tissue repair assembly of claim 10 wherein the first snare is configured to draw the first suture tail around the first and second external surfaces of the soft anchor and through the first suture locking passage.

17. The tissue repair assembly of claim 10 wherein tension on the first tail is configured to deploy the soft anchor and knotlessly lock the suture within the first suture locking passage.

18. A tissue repair assembly comprising:
a soft anchor having a proximal end and a distal end, a tubular sidewall and a longitudinal axis extending therebetween, the tubular sidewall defining a first external side surface and a second external side surface, the first and second external side surfaces on opposing sides of the soft anchor longitudinal axis and defining a maximum length of the soft anchor;
a suture threaded repeatedly through both the first and second external side surfaces, the suture having a first and a second suture tail extending from the soft anchor proximal end;
a first snare extending along the soft anchor and through a suture locking passage of the suture, the suture locking passage having a length at least as long as the soft anchor maximum length.

19. The tissue repair assembly of claim 18 further comprising a second snare extending along the soft anchor and through the suture locking passage of the suture.

20. The tissue repair assembly of claim 19 wherein the first and second snares both extend around the first and second external side surfaces and are configured to draw the first and second suture tails around the soft anchor and through the suture locking passage to form two closed suture loops, each of the two closed suture loops crossing over each other within the suture locking passage and emerging at opposite ends of the suture locking passage to each other.

21. An anchor assembly for knotlessly securing a bone to a repair tissue, the anchor assembly comprising:
an anchor body formed of braided threads in a tubular shape and having a distal end and a proximal end, the anchor body configured to adjust between an elongate configuration for insertion into the bone, and an expanded configuration for anchoring within the bone;
a suture defining a lumen, the suture is threaded along a first side of the anchor body, across the distal end and along an opposite side of
