Suture anchor, suture anchor installation device and method for attaching a suture to a bone

摘要

A suture anchor to secure a suture within a bore in a bone is disclosed, together with a suture anchor installation tool and method for deploying the suture anchor using the installation tool. The anchor includes a cylindrical body portion integrally associated with a generally conical-shaped end portion. At least one slot extends from the apex of the conical-shaped end portion into the cylindrical body portion forming at least two deformable tines. The tines flex toward one another as the anchor is inserted into the bore and are sufficiently resilient so as seek to return to an undeformed position once in the bone. The tines include outer edges disposed at the base of the conical-shaped end portions for preventing the suture anchor from being pulled out of the bore. The suture anchor installation tool includes an insertion member having an elongated body with a hollow interior sized so as to accommodate the suture anchor therein. The elongated body includes a suture loading assembly enabling a suture to be threaded through the slot while the anchor is fully retained in the elongated body.
