ANNULAR ACCESS DEVICE USING T-ANCHORS
First Claim
1. A suture locking device for use in closing an annulotomy of an intervertebral disc wherein the disc has an annulus, the device comprising:
- a plate including at least two suture holes wherein each hole is adapted to receive a suture attached to the annulus;
a rotatable actuator disposed adjacent to the plate and adapted to receive the sutures in such a manner that when the actuator rotates the sutures are wound together thereby securing the plate to the annulus; and
a release mechanism operatively coupled to the plate in such a manner that when the release mechanism is actuated the plate is released from the suture locking device.

Abstract
Suture locking devices and methods. In one embodiment, the device includes a suture lock, a rotatable actuator adjacent to the lock, and a release mechanism. The lock defines a pair of suture holes which receive sutures attached to tissue (e.g. a spinal disc) of the surgical site. When the actuator rotates the sutures are wound together (preferably around a hub on the lock) thereby securing the plate to the tissue. Furthermore, the release mechanism is coupled to the lock in such a manner that when the release mechanism is actuated the device releases the lock. The release mechanism may include a push button that is biased away from the lock. Also, the actuator may include a thumbwheel and a gear. Further, the gear may also define suture holes. Additionally, a pull ring connected to a pair of loops for drawing the sutures through the instrument may be included.

19. An instrument for use in closing a surgical site associated with a mass of tissue, the device comprising:
-
a proximal end;
a distal end adapted to receive a suture lock defining a pair of suture holes wherein each hole is adapted to receive a suture attached to the tissue;
a rotatable actuator disposed adjacent to the distal end and adapted to receive the sutures in such a manner that when the actuator rotates the sutures are wound together thereby securing the lock to the annulus; and

20. A method of closing a surgical site associated with a mass of tissue, the method comprising:
-
using a suture lock releasably attached to an instrument to receive a pair of sutures attached to the tissue;
drawing the sutures through the lock and through a rotatable member of the instrument, the rotatable member being disposed adjacent to the lock;
rotating the rotatable member whereby the sutures are wound together thereby securing the lock to the tissue; and
releasing the lock from the instrument. - View Dependent Claims (21, 22, 23, 24, 25, 26)
