Abstract
A device for cardiac surgery is disclosed. The device for cardiac surgery includes an aortic root retractor frame, an introducer, and one or more suture locking apparatuses. The device for cardiac surgery also includes an actuator for releasing the aortic root retractor frame, as well as a deployment mechanism for fully expanding the aortic root retractor frame. Multiple suture locking apparatuses used for releasable locking and unlocking of suture during a cardiac surgery procedure may be included in the device for cardiac surgery.
Claims8
A suture locking apparatus comprising:
- an upper housing having a first gripping surface;
- a lower housing coupled to the upper housing and having a second gripping surface;
- and
- a latch.
The suture locking apparatus of claim, w4herein the lower housing further comprises one or more cradles, each of the one or more cradles configured to engage one of the one or more hinges.
A method of stabilizing cardiac tissue, comprising:
- placing three commissural sutures in each of three commissures in an aortic annulus;
- loading each of the three commissural sutures into corresponding but separate suture locking apparatuses coupled to an aortic root retractor frame;
- delivering and positioning the aortic root retractor frame into an aortic root;
- tensioning and locking the commissural sutures into the corresponding but separate suture locking apparatuses;
- and
- deploying the aortic root retractor frame using a deployment suture coupled to the aortic root retractor frame.
