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 open mesh 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,

wherein an exterior of the heart is not completely covered by the open mesh material and therefore remains exposed to the surrounding tissue.

2. The device of claim 1, wherein the open mesh material comprises therapeutic agents.

3. The device of claim 2, wherein the therapeutic agents include growth factors or plasma proteins.

4. The device of claim 1, wherein the device is C-shaped so that blood flow is not impeded through the aorta and pulmonary artery when the device is implanted.

5. The device of claim 1, the implantable open mesh material further comprising edges and a center region, wherein the edges are more rigid than the center region of the open mesh material.
