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 device for use as an external stabilizer of a heart having a base and an apex, comprising a strip of biocompatible, implantable material having a predetermined size adapted to encompass the base of the heart and not the apex of the heart to prevent basal dilation during all cardiac cycle phases, and at least one chamber attached to the strip.

2. The device of claim 1, wherein the strip further comprising a top edge, a bottom edge and a center portion.

3. The device of claim 2, wherein the distance between the outside of the top edge and the outside of the bottom edge is between about 2 and about 5 cm.

4. The device of claim 2, wherein the center portion further comprises an open mesh.

5. The device of claim 4, wherein the open mesh further comprises opening sizes between 2 mm to 2 cm, when measured long the longest axis.

6. The device of claim 2, where in the top and bottom edge further comprise a metal.

7. The device of claim 2, wherein the center portion further comprises a polyester mesh.

8. The device of claim 1, further comprising means for attaching the device to the heart.

9. The device of claim 1, further comprising attachment members.

10. The device of claim 9, wherein the attachment members further comprise eyelets.

11. A method for treating heart disorders comprising epicardial placement of a device according to claim 1 around the base of the heart.

12. The method of claim 11, further comprising placing the device in the atrioventricular groove.
