System and method for attaching soft tissue to bone
First Claim
1. A method of attaching soft tissue to bone, comprising:
- inserting a first anchor into bone;
passing a first suture from said first anchor over an edge of the soft tissue;
coupling the first suture to an anchor-inserter assembly comprising a distal member, a proximal member comprising a central bore extending therethrough, a tube butting against a proximal end of said proximal member, a central inserter member extending through said tube and said central bore to said distal member, and a handle coupled to said tube;
inserting the distal member of the anchor-inserter assembly into bone at a position beyond the edge of the soft tissue, wherein inserting the distal member comprises directly forcing the distal member into the bone without pre-drilling a hole in the bone, wherein after insertion of said distal member into the bone, the proximal member is positioned above the surface of the bone;
after inserting the distal member of the anchor-inserter assembly, tensioning the first suture to compress an area of tissue to bone between the edge of the soft tissue and the first anchor, wherein after said tensioning of the first suture, the first anchor position is underneath the soft tissue; and
after tensioning the first suture, moving said proximal member distally toward said distal member by relative movement between the tube and the central inserter member, wherein said distal movement of the proximal member fixedly secures the first suture at the second anchor position without tying any knots.

Abstract
Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A bone anchor is described that comprises a base and a top such that suture material may be compressed between surfaces on the base and top to secure the suture to the anchor. Also described is an inserter that can be used to insert the bone anchor into bone and move the anchor top relative to the anchor base to clamp suture material there between. Also described is a soft-tissue and bone piercing anchor and associated inserter. Methods are described that allow use of the bone anchors to provide multiple lengths of suture material to compress a large area of soft tissue against bone.

10. A method of attaching soft tissue to bone, comprising:
-
inserting a first anchor into bone in a first anchor position; passing a first suture from said first anchor over an edge of the soft tissue; and securing the first suture at a second anchor position beyond the edge of the soft tissue to compress an area of tissue to bone between the edge of the soft tissue and the first anchor, wherein after said securing, the first anchor position is underneath the soft tissue, and wherein said securing comprises; forming a hole in bone at said second anchor position, coupling the first suture to an anchor-inserter assembly comprising a distal member, a proximal member comprising a central bore extending therethrough, a tube butting against a proximal end of said proximal member, a central inserter member extending through said tube and said central bore to said distal member, and a handle coupled to said tube, inserting the distal member of the anchor-inserter assembly in the hole, wherein after insertion of said distal member into the hole, the proximal member is positioned above the surface of the bone, after inserting the distal member of the anchor-inserter assembly, tensioning the first suture, and moving said proximal member distally toward said distal member by relative movement between the tube and the central inserter member, wherein said distal movement of the proximal member fixedly secures the first suture at the second anchor position without tying any knots. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
