Implant and delivery system for soft tissue repair
First Claim
1. A method for repairing tissue, comprising:
- positioning an inserter of an inserter assembly preloaded with a first and second anchor in proximity to bone;
implanting with the inserter the first anchor with a first end of suture or wire fixedly coupled to the first anchor through the tissue and into a first region of bone;
observing a first depth indicator disposed on the inserter assembly to indicate a suitable depth of insertion of the first anchor within the first portion of bone;
implanting with the inserter the second anchor through the tissue and into a second region of bone observing a second depth indicator disposed on the inserter assembly to indicate a suitable depth of insertion of the second anchor within the second portion of bone;
wherein a portion of the suture or wire is slidingly routed through the second anchor and wherein the first anchor and second anchor are separated by a region of tissue to be repaired;
tensioning the suture or wire between the first and second anchors; and
locking the suture or wire with respect to the first and second anchors such that the region of tissue to be repaired is affixed to the bone; and
wherein the step of locking the suture or wire with respect to the first and second anchor comprises actuating a suture plug member retained within the second anchor so as to lock the suture or wire relative to the second anchor.

Abstract
Implant and delivery systems for soft tissue repair which affix soft tissue portions to a region of bone are described. Generally, the assembly includes two bone anchors preloaded through an inserter handle such that each anchor is penetrated into the bone directly. The first anchor is inserted through the tissue and into the bone, where it is locked into position. The first anchor has a suture or wire that protrudes through the tissue and threads through the second anchor and is secured to a rotatable suture reel located along the handle. The second anchor is inserted through the tissue and into the bone independently of the first anchor. Once the second anchor is deployed, the suture or wire is tensioned to secure the soft tissue to the bone and a suture plug within the second anchor is deployed to lock the suture or wire in place.

10. A method for affixing an articular supraspinatus tendon to a humeral head, comprising:
-
positioning an inserter of an inserter assembly preloaded with a first and second anchor in proximity to the humeral head; implanting with the inserter a first anchor through a first portion of the tendon and into a first region of the humeral head, the first anchor having a suture or wire fixedly connected within the first anchor; observing a first depth indicator disposed on the inserter assembly to indicate a suitable depth of insertion of the first anchor within the first portion of the humeral head; implanting with the inserter a second anchor through a second portion of the tendon and into a second region of the humeral head, wherein the first anchor and second anchor is separated by a distance, the second anchor having a portion of the suture or wire slidingly routed through the second anchor and also routed adjacent an anchor plug retained within the second anchor; observing a second depth indicator disposed on the inserter assembly to indicate a suitable depth of insertion of the second anchor within the second portion of the humeral head; tensioning the suture or wire between the first and second anchors and sliding the anchor plug to lock the suture or wire within the second anchor such that the tendon is affixed to the humeral head.

11. A method of repairing a piece of soft tissue, comprising:
-
inserting a first anchor through a first portion of soft tissue and into a first portion of bone, said first anchor detachably connected with a distal end of a first support sleeve within a first inserter shaft of an inserter assembly; observing a first depth indicator disposed on the inserter assembly to indicate a suitable depth of insertion of the first anchor within the first portion of bone; locking said first anchor with the first portion of bone ;
detaching said first anchor from said first support sleeve;
inserting a second anchor through a second portion of soft tissue spaced away from the first portion of soft tissue and into a second portion of bone, said second anchor detachably connected with a distal end of a second support sleeve within a second inserter shaft of the inserter assembly;observing a second depth indicator disposed on the inserter assembly to indicate a suitable depth of insertion of the second anchor within the second portion of bone; locking said second anchor with second portion of bone;
adjusting the tension of a connecting member that is fixedly connected with the first anchor and slidingly routed through the second anchor, said connecting member also connected with the inserter assembly, so as to repair the piece of soft tissue; anddetaching the second anchor from the second support sleeve;
wherein before the step of detaching the second anchor, actuating a suture plug retained within the second anchor so as to lock the connecting member relative to the second anchor. - View Dependent Claims (12)
