General Description
[0017] Suture anchors have previously been utilized to retain sutures in either hard or soft tissue in a human patient's body. The suture anchors have previously been formed of metal, biodegradable materials, and other materials which do not naturally occur in a patient's body. The insertion of materials other than body tissue into a patient's body may be objectionable.
[0018] In accordance with a feature of the present invention, sutures are retained in a patient's body by anchors formed of body tissue. In one specific embodiment of the invention, the anchor is formed of bone or osseous (bonelike) tissue. In another embodiment of the invention, the anchor is formed of dense connective body tissue. The dense connective body tissue may contain collagen. The dense connective body tissue may be cartilage, tendon or ligament. The dense connective body tissue may be interarticular fibrocartilage which previously formed a meniscus in a joint. Although it is believed t...

Abstract
An improved suture anchor is formed from body tissue. The body tissue is shaped to a desired configuration for the anchor and defines a passage through the anchor. A suture is inserted into the passage in the body tissue of the anchor. The anchor is then positioned in a patient's body with a suture extending into the passage in the anchor. The anchor may be formed of osseous body tissue, hard compact bone, dense connective body tissue, or other body tissue. The body tissue may be dried so that it absorbs fluid and expands upon being inserted into a patient's body
