Abstract

A method for heart valve surgery may include providing a cardiac valve ring and suture loops connected to the cardiac valve ring, accessing a valve annulus of the heart of the patient, stapling at least one of the sutures loop to the valve annulus, and parachuting the cardiac valve ring down the suture to the valve annulus after the stapling. The cardiac valve ring may be an annuloplasty ring, a replacement heart valve, or other medical device.

Claims

1. A surgical method performed on a valve annulus of the heart of a patient, the heart including a natural heart valve composed of native tissue of the patient, where the valve annulus is located adjacent to the natural heart valve, comprising:

providing an annuloplasty ring and a plurality of suture loops connected to said annuloplasty ring, said suture loops formed from lengths of suture wherein at least one of said suture loop is U-shaped;

accessing the valve annulus of the heart of the patient, adjacent to the natural heart valve;

stapling at least one said suture loop to the valve annulus with at least one staple; and

moving said annuloplasty ring down said suture to the valve annulus to a position adjacent to the natural heart valve, after said stapling.

2. The method of claim 1, wherein said stapling includes straddling said suture of said suture loop with said staple, and closing said staple after said straddling.

3. The method of claim 2, wherein said stapling includes penetrating the valve annulus with said staple before said closing.

4. The method of claim 1, further comprising holding said annuloplasty ring in a fixed position relative to said valve annulus after said moving.

5. The method of claim 1, wherein said moving is along said suture in only a single direction.

6. The method of claim 1, further comprising severing at least one said suture in proximity to said cardiac valve ring after said moving.

7. The method of claim 1, further comprising splaying at least one said staple before said stapling.

8. The method of claim 1, wherein said stapling comprises successively stapling individual suture loops.

9. The method of claim 1, wherein each length of suture has a first end and a second end, further comprising tying said first end of at least one said suture to said second end.
