Abstract

A device for locking a suture in place without the need for tying knots once the suture is placed within tissue is provided. The device comprises an anchor having a cannula and a locking mechanism for securing the suture within the cannula.

Claims

1. A device for locking a suture in place, comprising:

an anchor having a front section and a rear section, a cannula extending through the front and rear sections for extending the suture therethrough, the rear section including a first rear portion and a second rear portion, and

a push locking ring sized to receive the rear section of the anchor therein and compress the first rear portion and the second rear portion to lock the suture therebetween within the cannula, wherein the push locking ring is connected to the anchor by a frangible portion that is broken upon movement of the push locking ring toward the anchor.

2. A device for locking a suture in place, comprising:

an anchor having a front section and a rear section, a cannula extending through the front and rear sections for extending the suture therethrough, the rear section including a first rear portion and a second rear portion, and

a push locking ring configured to receive the rear section of the anchor therein and compress the first rear portion and the second rear portion to lock the suture therebetween, wherein the push locking ring is connected to the anchor by a frangible portion that is broken when the push lock ring is placed in a locked position and said rear section of the anchor comprises a lip recessed from the rear section surface and positioned to contact an edge of the push locking ring when the push locking ring is placed in a locked position thereby restraining the push locking ring.

3. A device for locking a suture in place, comprising:

an anchor having a front section and a rear section, a cannula extending through the front and rear sections for extending the suture therethrough, the rear section including a first rear portion and a second rear portion, and

a push locking ring sized to receive the rear section of the anchor therein and compress the first rear portion and the second rear portion to lock the suture therebetween, wherein the push locking ring is connected to the anchor by a frangible portion that is broken when the push locking ring is placed into a locked position.
