Abstract
Methods and devices are provided for attaching soft tissue to bone. In general, a deployment device, insertion assembly, and suture anchor are provided. The insertion assembly is coupled between the deployment device and the suture anchor to allow the deployment device to deploy the suture anchor into bone. Each of the various components disclosed herein can be used alone, in combination with one another, or in combination with various other devices.
Claims9
1-7. (canceled)
A suture anchor assembly, comprising:
- a suture anchor having an insert with a suture mated thereto, and a sleeve disposable over the insert and configured to lock the suture between the insert and the sleeve;
- and
- a deployment device having a housing with a suture tensioning element mated to the suture for tensioning the suture between the insert and the suture tensioning element, and an actuation mechanism movably coupled to the housing and having a distal end mated to the sleeve such that the actuation mechanism is configured to position the sleeve over the insert while the suture remains fixed between the tensioning element and the insert and wherein when the sleeve is positioned over the insert the suture is frictionally trapped between an inside surface of the sleeve and an outside surface of the insert.
14-23. (canceled)
A suture anchor assembly, comprising:
- a suture anchor having an insert with a suture mated thereto, and a sleeve disposable over the insert in a first position in which the suture is slidable with respect to the insert;
- a deployment device having a housing with a suture tensioning element mated to the suture for tensioning the suture between the insert and the suture tensioning element, and an actuation mechanism movably coupled to the housing and having a distal end mated to the sleeve such that the actuation mechanism is configured to retract the sleeve into a second position over the insert toward the housing while the suture remains fixed between the tensioning element and the insert and the insert remains fixed with relation to the housing;
- and
- wherein when the sleeve is in the second position the suture is frictionally trapped between an inside surface of the sleeve and an outside surface of the insert.
