SYSTEM AND METHOD FOR ATTACHING SOFT TISSUE TO BONE
First Claim
1. A bone implant, comprising:
- a substantially hollow cylinder comprising bone-engaging protrusions configured to prevent removal of the implant from bone; and
a bone-piercing tip that comprisesa distal portion comprising a pointed tip configured to pierce through bone,a medial portion comprising a transverse suture aperture, anda proximal portion having a smaller diameter than the medial portion and configured to couple to an inserter.

Abstract
Methods and devices for securing soft tissue to a rigid material such as bone are disclosed herein. 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.

14. A method of fixating a bone implant within bone, comprising:
-
providing a bone implant, comprising; a substantially hollow cylinder, and a bone-piercing tip comprising a distal portion having a pointed tip, a medial portion having a suture aperture, and a proximal portion; providing an inserter, comprising; a handle, an outer sleeve fixed to the handle, and an inner tube positioned within the outer sleeve, wherein the bone implant is coupled to a distal end of the inserter and a suture material passes through the suture aperture of the bone implant and through the inner tube and handle of the inserter; inserting the bone implant into bone; moving the inner tube axially relative to the outer sleeve; detaching the bone implant from the inserter; and withdrawing the inserter from the bone, such that the suture material and the bone implant remain within the bone. - View Dependent Claims (15, 16, 17, 18, 19)
