Abstract

The present disclosure is directed to an external cardiac basal annuloplasty system (ECBAS or BACE-System: basal annuloplasty of the cardia externally) and methods for treatment of regurgitation of mitral and tricuspid valves. The BACE-System provides the ability to correct leakage of regurgitation of the valves with or without the use of cardiopulmonary bypass, particularly when the condition is related to dilation of the base of the heart. This ECBAS invention can be applied to the base of the heart epicardially, either to prevent further dilation or to actively reduce the size of the base of the heart.

Claims

1. A method of treating a heart disorder, comprising:

(a) placing a device comprising a biocompatible mesh material, having a predetermined size adapted to encompass a base of a heart, and having at least one chamber attached thereto, around the base of the heart, the biocompatible mesh material having edge portions with attachment members extending therefrom; and

(b) exerting support on the base of the heart by the chamber after being placed around the base of the heart, wherein the support exertion prohibits an increase of at least a portion of the base of the heart beyond a pre-determined size.

2. The method of claim 1, wherein the at least one chamber is inflatable.

3. The method of claim 1, wherein the at least one chamber is fluid fillable.

4. The method of claim 1, wherein the at least one chamber is fluid filled.

5. The method of claim 1, wherein the mesh material comprises an inner portion and an outer portion, and the at least one chamber is positioned on or contacting the inner portion of mesh material.

6. The method of claim 1, wherein the device is placed in the atrio-ventricular groove of the heart.

7. The method of claim 1, wherein the device is placed along the posterior aspects of the base of the heart.

8. The method of claim 1, wherein the device is placed in the mitral and tricuspid portion of the heart.

9. The method of claim 1, wherein the device stabilizes the mitral and tricuspid annuli of the heart when placed around the heart.

10. The method of claim 1, wherein the at least one chamber increases passive transfer of energy to at least one portion of the base of the heart.

11. The method of claim 1, wherein the exerted support is sufficient to prevent basal dilation during all cardiac cycle phases.

12. The method of claim 1, wherein the exerted support provides a localized increase in contraction at one or more locations of the base.

18. The method of claim 1, wherein the attachment members are securing eyelets.

13. A device for use as an external stabilizer of a heart having a base and an apex, comprising a biocompatible mesh material having a predetermined size adapted to encompass the base of the heart to prevent basal dilation during all cardiac cycle phases heart, the biocompatible mesh material having edge portions with attachment members extending therefrom, and at least one chamber attached to the biocompatible mesh material.

14. The device of claim 13, wherein the at least one chamber is inflatable.

15. The device of claim 13, wherein the at least one chamber is fluid fillable.

16. The device of claim 13, wherein the at least one chamber is fluid filled.

17. The device of claim 13, wherein the mesh material comprises an inner portion and an outer portion, and the at least one chamber is positioned on or contacting the inner portion of the mesh material.

19. The device of claim 13, wherein the attachment members are securing eyelets.
