Abstract
Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue capture anchor is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and spreader and inside surfaces of a bone hole to secure the tissue within the hole. A bone anchor is described that comprises an anchor body with expandable tines and a spreader that expands the tines into bone. The spreader captures tissue via a suture loop at the distal end of the bone anchor. Also described is an inserter that can be used to insert the anchor into bone and move the spreader within the anchor to expand the anchor and capture the tissue between the anchor and the bone. Methods are described that allow use of single bone anchor to secure tissue to bone or also to use more than one bone anchor to provide multiple lengths of suture material to compress a large area of soft tissue against bone.
