System and method for attaching soft tissue to bone
First Claim
1. An anchor for securing a suture to bone, said anchor comprising:
- a substantially hollow cylinder comprising an open end and comprising a portion of its walls cut in such a manner so as to allow the cylinder to deform under stress and form lateral protrusions;
a substantially pointed tip coupled to the cylinder opposite the open end, wherein the pointed tip is adapted to pierce the bone; and
a suture receiver coupled to said pointed tip and positioned so that a suture may be attached to the suture receiver and extend longitudinally through the cylinder and out of the open end.

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.

11. A bone anchor, comprising:
- a cylindrical body having cuts formed in its side such that the body can deform under axial force to form one or more lateral features, wherein at least some of the cuts define two convex edges adapted to continuously roll against each other during deformation; and
a suture receiver positioned so that a suture may be attached to the suture receiver and extend longitudinally through the cylinder. - View Dependent Claims (12, 13, 14, 15)
- a cylindrical body having cuts formed in its side such that the body can deform under axial force to form one or more lateral features, wherein at least some of the cuts define two convex edges adapted to continuously roll against each other during deformation; and
- 16. A bone anchor, comprising a substantially hollow cylindrical body having an open end and a substantially pointed tip comprising a suture receiver positioned opposite the open end, the substantially hollow cylindrical body having cuts formed in its side such that the body can deform under axial force to form one or more lateral features, wherein at least some of the cuts define one or more hinges about which a first portion of the side of the body can bend during deformation and define an edge of said first portion adapted to contact a second portion of the side of the body, wherein said first portion forms part of one of the lateral features after deformation, wherein a suture may be attached to the suture receiver and extend longitudinally through the cylinder and out of the open end.

24. A bone anchor, comprising:
-
a substantially hollow cylinder comprising a plurality of cuts in the side of the cylinder configured to allow the cylinder to deform under stress and comprising a proximal open end and a distal open end; and a pointed tip comprising a suture receiver positioned so that a suture may be attached to the suture receiver and extend longitudinally through the cylinder and out of the proximal open end, wherein the pointed tip is configured to pierce a bone and connect to the suture receiver, wherein the pointed tip is attached to the distal open end of the substantially hollow cylinder. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
