Abstract
A self-seating, non-linear suture anchor system and method of insertion is disclosed where the anchor is made up of a non-linear or curved anchor. The anchor has at least one hole for one or more sutures such that the anchor can be introduce through a small opening, incision, channel or cannula in a confined space and inserted at an angle different than, or divergent from, the angle determined by the cannula, opening or the confines of the space.
Claims34
A suture anchor and delivery assembly, comprising:
- an elongated, non-linear anchor body with a first end and a second end, at least one hole is formed in the anchor body for the passage of a suture therethrough, the anchor body including an attachment site at a second end thereof;
- a control rod shaped and dimensioned for attachment to the attachment site of the anchor body, the control rod includes a distal end constructed of a flexible materials allowing for displacement of the control rod;
- and
- a guide for the insertion of the anchor.
A method for attaching sutures to body tissue, such as bone or cartilage to repair injuries to tendons, ligaments, cartilage and other connecting structures in the body by application of a bone anchor in a non-linear, non-co-linear or a divergent angle to the insertion angle required to approach the anatomic structure as dictated by the confines of the local anatomy, comprising:
- forming a tunnel within an anatomical site;
- positioning a guide adjacent the tunnel, the guide including an angled outlet end having an opening transverse to the longitudinal axis of the guide.
- passing a bone anchor through the guide to, and out of the outlet end of the guide;
- positioning the anchor with the tunnel;
- and
- seating and locking the anchor in the tunnel.
A suture anchor for use in non-linear, non-co-linear or divergent angle deployment, comprising:
- an anchor body including a first end and a second end, at least one hole is formed in the anchor body for the passage of a suture therethrough, the anchor body including an attachment site at a second end thereof;
- wherein the anchor body is triangular in shape when viewed along a cross section taken perpendicular to a longitudinal axis of the anchor body.
A control rod for a suture anchor and delivery assembly, comprising:
- an elongated rod body shaped and dimensioned for attachment to an attachment site of the anchor body, the rod body includes a distal end constructed of a flexible materials allowing for displacement of the control rod;
- the rod body further including a substantially rigid straight section along a proximal end thereof and a flexible section at a distal end, the flexible section being weakened by removal of material or the formation of cuts in the flexible section of the rod body.
