Swivel anchor for knotless fixation of tissue
First Claim
Patent Images
1. A method of knotless tissue fixation comprising:
- providing a suture;
securing the suture to tissue to be fixated;
preloading a cannulated fixation device on a shaft of a driver;
capturing the suture attached to the tissue with an implant, the implant being releasably attached at a distal end of the driver, the implant being configured to swivel relative to the cannulated fixation device;
inserting the implant and the captured suture into bone; and
anchoring the suture into the bone by rotating the driver to rotate and advance the cannulated fixation device while keeping the implant stationary, thereby securing the suture and providing tissue fixation without tying any knots in the suture.

Abstract
A method and device for knotless fixation of tissue. A swivel anchor having a rotatable implant is used to capture suture for surgical tissue repair without requiring suture knots. The implant may be provided with a conical metal tip which is self-punching and avoids the need for pre-drilling a hole in bone. The implant includes a closed aperture to allow free sliding of a suture strand. The swivel anchor is secured in a hole in bone by advancing a fixation device, such as a cannulated interference screw, over the body of the implant.
