This device aims at correcting distortions in spatial geometry and function of the heart muscle, thereby restoring valvular integrity and optimizing myocardial performance. The device is applied externally to the heart, fixed in the chest cavity or wall, while maintaining flexibility and selectively targeting specific points of varying size, tension, and force requirements. This minimally invasive device and method of application will contribute toward a reduced rate of mortality and morbidity from heart disease.

DETAILED DESCRIPTION The objects set forth,, above as well as further and other objects and advantages of the present invention, are achieved by the embodiments of the invention described hereinbelow.
The present invention related to a device, which could deliver the targeted localized force, tension and displacement changes with a minimally invasive approach.
It would prevent inordinate tension placed on the mitral valve or the relative stenosis that could occur with annuloplasty techniques.
The present invention relates more particularly to the restoration of mitra valve competency and compensates for the regional ventricular dysfunction in general and strain induced by papillary muscle tethering.
It corrects for the displacement and forces on leaflet closure.
An advantage of the localized force and displacement change, a feature of this device, is to avoid coronary flow impedance, minimize damage, and maximize impact.
One feature of the present invention is its stability around the heart, diverting fixation tension, leverage and stress from the heart to the rib cage; therefore delivering force or tension required to the specific point.
For a better understanding of the present invention, together with other and further objects thereof, reference is made to the accompanying drawings and detailed description and its scope will be pointed out in the appended claims.
