Abstract
In one embodiment, a method of repairing a heart valve accesses an interior of a patient's beating heart minimally invasively and inserts one or more sutures into each of a plurality of heart valve leaflets with a suturing instrument. The suture ends of the sutures are divided into suture pairs, with each pair including one suture end from a suture inserted into a first valve leaflet and one suture end from a suture inserted into a second valve leaflet. One or more tourniquet tubes is advanced over the suture pairs to the leaflets to draw the sutures together to coapt the leaflets and then the sutures are secured in that position.
Claims18
A method of minimally invasively performing an edge to edge heart valve leaflet repair on a beating heart of a patient, comprising:
- accessing an interior of a beating heart of a patient minimally invasively;
- inserting one or more sutures into each of a first valve leaflet and a second valve leaflet of a heart valve in the beating heart of the patient, each suture having a pair of suture ends;
- providing a plurality of suture pairs, each suture pair including one of the pair of suture ends of a suture inserted through the first valve leaflet and one of the pair of suture ends of a suture inserted through the second valve leaflet;
- advancing one or more tourniquet tubes over the suture pairs towards the heart value such that the sutures are drawn into a coaptation tension in which the first valve leaflet and the second valve leaflet are in a coapted position;
- securing the sutures at the coaptation tension;
- withdrawing the one or more tourniquet tubes from the suture ends after securing the sutures;
- and
- anchoring the suture ends at a wall of the heart with the sutures in the coaptation tension,
- wherein securing the sutures at the coaptation tension includes:
- securing the one or more tourniquet tubes with respect to the suture pairs with the sutures in the coaptation tension;
- advancing a suture loop of a ligature suture along the one or more tourniquet tubes to the first valve leaflet and the second valve leaflet;
- and
- securing the suture loop around the sutures with the sutures in the coaptation tension.
