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 system for minimally invasively performing an edge to edge heart valve leaflet repair on a beating heart of a patient, comprising:
- a suturing device configured to grasp and stabilize each of a first valve leaflet and a second valve leaflet to minimally invasively insert one or more sutures into each of the first valve leaflet and the second valve leaflet of a heart valve in the beating heart of a patient, each suture having a pair of suture ends;
- a tourniquet tube configured to be advanced towards the heart valve over a plurality of suture pairs 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, wherein each suture pair includes 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;
- and
- means for securing the sutures with the sutures in the coaptation tension,
- wherein the tourniquet tube is configured to be withdrawn from the suture ends following securement of the sutures, and
- wherein the suture ends are configured to be anchored at a wall of the heart with the sutures in the coaptation tension.
A system for minimally invasively performing an edge to edge heart valve leaflet repair on a beating heart of a patient, comprising:
- a suturing device configured to minimally invasively insert 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 a patient, each suture having a pair of suture ends;
- a tourniquet tube configured to be advanced towards the heart valve over a plurality of suture pairs 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, wherein each suture pair includes 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;
- and
- means for securing the sutures with the sutures in the coaptation tension,
- wherein the tourniquet tube is configured to be withdrawn from the suture ends following securement of the sutures, and
- wherein the suture ends are configured to be anchored at a wall of the heart with the sutures in the coaptation tension, and
- further comprising a plurality of tourniquet tubes including a separate tourniquet tube for each suture pair.
A system for minimally invasively performing an edge to edge heart valve leaflet repair on a beating heart of a patient, comprising:
- a suturing device configured to grasp and stabilize each of a first valve leaflet and a second valve leaflet to minimally invasively insert one or more sutures into each of the first valve leaflet and the second valve leaflet of a heart valve in the beating heart of a patient, each suture having a pair of suture ends;
- a tourniquet tube configured to be advanced towards the heart valve into contact with the first valve leaflet and the second valve leaflet over a plurality of suture pairs such that the one or more sutures in the first valve leaflet and the one or more sutures in the second valve leaflet are drawn into a coaptation tension by the tourniquet tube in which the first valve leaflet and the second valve leaflet are in a coapted position, wherein each suture pair includes 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;
- and
- wherein the tourniquet tube is configured to be withdrawn from the suture ends following securement of the sutures at the coaptation tension, and
- wherein the suture ends are configured to be anchored at a wall of the heart with the sutures in the coaptation tension.
