First Claim
Patent Images
1. A method of effecting therapeutic reparation of a location of a body comprising:
- a) disposing soft tissue repair material in the location of the body; and
b) securing an anchor of a fixation device into a cavity in bone tissue proximate the location of the body, the anchor having a first end and a second end, the anchor further having an exterior surface including one or more raised ribs, and further the one or more raised ribs are each oriented in a direction parallel to an axis of the anchor, the fixation device further comprising a material retention member extending radially from the anchor in a plurality of directions, such that at least one contact surface of the material retention member engages a portion of the soft tissue repair material that is interposed between the material retention device and the bone tissue,wherein the anchor includes a shoulder portion extending from a location on the anchor between the first and second end toward a location proximate the first end of the anchor, and wherein step b) further comprises securing the anchor within the cavity by advancing the anchor into the cavity until at least a portion of the shoulder contacts the bone tissue.

Abstract
An apparatus for use in affixing material to a location under repair includes a material retention member and an anchor. The anchor is configured to be inserted into a cavity in bone tissue, the anchor having a first end and a second end. The anchor also includes one or more raised ribs. The material retention member extends radially from the first end of the anchor in a plurality of directions, the material retention member including at least one contact surface adapted to exert a retention force on material that is interposed between the material retention device and the bone tissue.
