Abstract

A suture locking assembly for use with a heart valve repair device. The suture locking assembly including a rim and a suture band. The rim defines a first flange and a second flange spaced from the first flange. The rim is configured to extend at least partially around a periphery of the heart valve repair device. The suture band is maintained between the first flange and the second flange. The suture locking assembly is configured to securely maintain a suture segment that is pulled from a first position to a second position relative the suture locking assembly, the second position being at least partially defined near an outer periphery of the rim.

Claims

1. A method of implanting a heart valve repair device, the method comprising:

providing a heart valve repair device;

receiving a suture locking assembly including;

a rim extending along an outer periphery of the heart valve repair device, the rim defining a first flange and a second flange spaced from the first flange, and

a suture band maintained between the first flange and the second flange;

positioning the heart valve repair device, and the suture locking assembly within a patient;

sewing a suture through a patient'"'"'s valvular rim in a first position relative the rim and the suture band;

wherein the suture extends at least partially between the rim and the suture band in the first position; and

pulling the suture to a second position relative the rim and the band, wherein the suture is secured with respect to the rim and the suture band in the second position, the second position is at least partially defined near an outer periphery of the rim;

wherein securing the suture in the second position at least partially secures the heart valve repair device with respect to the patient'"'"'s valvular rim.

2. The method of claim 1, wherein the suture extends at least partially between the rim and the suture band in the second position.

3. The method of claim 1, wherein the rim is integrally formed with the heart valve repair device.

4. The method of claim 1, wherein the rim is formed separately from the heart valve repair device.

5. The method of claim 1, wherein the step of receiving a suture locking assembly includes placing the rim adjacent an external portion of the heart valve repair device.

6. The method of claim 1, wherein the rim forms a plurality of lateral recesses periodically spaced about the rim, each of the lateral recesses defining a first position for one of the plurality of sutures, and the step of sewing a suture in a first position is repeated for each of the plurality of lateral recesses.

7. The method of claim 6, wherein pulling the sutures to a second position includes pulling each of the sutures in a first direction with respect to the first position of the suture.

8. The method of claim 6, wherein the step of sewing a suture in a first position is repeated twice for each of the plurality of lateral recesses.

9. The method of claim 8, wherein pulling the sutures to a second position includes pulling at least one of the sutures from the first position in a first direction and pulling at least one of the other sutures from the first position in a second direction to cross the sutures pulled in the first and second directions.

10. The method of claim 9, wherein sewing a suture in a first position for each of the plurality of recesses includes crossing two of the suture with one another.

11. The method of claim 6, wherein the rim defines a plurality of second positions, each second position being spaced between each of the plurality of lateral recesses, the step of pulling the suture to a second position is repeated for each of the sutures sewn in a first position.

12. The method of claim 6, wherein the rim defines a plurality of second positions, two second positions being defined between each of the plurality of lateral recesses, the step of pulling a suture to a second position is repeated for each of the sutures sewn in a first position.

13. The method of claim 1, wherein the suture band defines a U-shaped cutout, and pulling the suture to a second position includes pulling the suture into the U-shaped cutout.

14. The method of claim 1, wherein the suture band defines an engagement section including a connecting body flanked by an outflow cut and an inflow cut, and pulling the suture to a second position includes pulling the suture through the inflow and outflow cuts.

15. The method of claim 14, wherein the suture band defines at least one lateral stop, and pulling the suture to a second position includes pulling the suture over the at least one lateral stop rib.

16. The method of claim 1, wherein sewing a suture in a first position is repeated for a plurality of sutures, and pulling the suture to a second position includes forming a hitch with two adjacent sutures.

17. The method of claim 16, wherein pulling the suture to a second position includes pulling the hitch to position the hitch between the rim and the suture band.

18. The method of claim 1, wherein the step of pulling the sutures to a second position includes using a suture holder to pull the sutures.
