Abstract
A method and apparatus for reattaching soft tissue to a boney structure using an expanding suture anchor. The method can include providing a suture anchor and forming a cavity in the boney structure for receipt of the suture anchor. The method can also include coupling the soft tissue to a suture and coupling the suture to the suture anchor. The method can further include deploying the suture anchor to fix the suture to the suture anchor and the suture anchor to the cavity.
Claims24
A method for attaching a soft tissue to a boney structure comprising:
- forming a cavity in a boney structure;
- passing a suture having first and second ends through a soft tissue;
- passing the first and second ends of the suture into a suture-receiving opening of an insert of a suture anchor;
- inserting the suture anchor into the cavity;
- applying a retractive force on the insert through a sleeve of the suture anchor;
- pivoting an expanding element of the sleeve with the insert, the expanding element defined by a U-shaped slot formed in a midsection of the sleeve so as to be spaced apart from a proximal end and a distal end of the sleeve and surrounded by the sleeve, the U-shaped slot defining three sides of a periphery of the expanding element, with a fourth side of the periphery of the expanding element hingeably coupled to the midsection of the sleeve;
- and
- anchoring first and second portions of the suture in contact with a wall of the cavity and the sleeve of the suture anchor without a knot.

A method for attaching a soft tissue to a boney structure comprising:
- forming a cavity in a boney structure;
- passing a suture having first and second ends through a soft tissue;
- opening first and second hinged portions attached to first and second open ends of a through bore of an insert of the suture anchor;
- passing the first and second ends of the suture into the through bore;
- closing the first and second hinged portions;
- inserting the suture anchor into the cavity;
- applying a retractive force on the insert through a sleeve of the suture anchor;
- pivoting an expanding element of the sleeve with the insert, the expanding element defined by a U-shaped slot formed in a midsection of the sleeve so as to be spaced apart from a proximal end and a distal end of the sleeve and surrounded by the sleeve, the U-shaped slot defining three sides of a periphery of the expanding element, with a fourth side of the periphery of the expanding element hingeably coupled to the midsection of the sleeve;
- retaining the suture in the through bore by pivoting the first and second hinged portions to close the through bore;
- and
- anchoring first and second portions of the suture in contact with a wall of the cavity and the sleeve of the suture anchor without a knot.

A method for attaching a soft tissue to a boney structure comprising:
- forming a cavity in a boney structure;
- passing a suture having first and second ends through a soft tissue;
- passing a first end of the suture transversely into a C-shaped slot of an insert of a suture anchor, the C-shaped slot having a first through bore and a necked portion;
- coupling the second end of the suture directly to a breakaway portion of the insert;
- inserting the suture anchor into the cavity;
- applying a retractive force on the insert through a sleeve of the suture anchor;
- pivoting an expanding element hingedly coupled at a midsection of the sleeve;
- expanding the sleeve;
- and
- anchoring first and second portions of the suture in contact with a wall of the cavity and the sleeve of the suture anchor.

- coupling the second end of the first suture directly to a breakaway portion of the insert;
- passing a second suture through a second through bore of the insert, the second through bore not communicating with the first through bore;
- inserting the suture anchor into the cavity;
- applying a retractive force on the insert through a sleeve of the suture anchor;
- expanding the sleeve;
- coupling the second suture to a second suture anchor;
- and
- anchoring first and second portions of the first suture in contact with a wall of the cavity and the sleeve of the suture anchor.
