Method and apparatus for external stabilization of the heart valves and myocardium
First Claim
1. A device for use as an external heart stabilizer to provide both valvular stabilization and myocardial reinforcement, wherein the heart has a base and an apex, comprising:
- (a) a strip of biocompatible, implantable material having a predetermined width 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
(b) an extension comprising a biocompatible, implantable material to provide mechanical myocardial reinforcement, wherein the extension is operably connected to the strip.

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. Such devices also include an extension thereto for the treatment of localized myocardial defects, scars and damage.
