Abstract
Abstract 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.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
130 words
An adjustable periventricular device for a patient, comprising: supporting brackets attachable to different surfaces, curvatures, and geometric orientations of one or more portions of the patient in the region of the heart; swiveling adjustable arched arms being adjustable in width and length to different surfaces, curvatures, and geometric orientations, having a hinge point; a center part on which said swiveling adjustable arched arms rest, said center part fixable to the patient's diaphragm; pressure heads affixable to different surfaces, curvatures, and geometric orientations of a patient's heart to provide corrective forces thereto, said pressure heads being held by said swiveling adjustable arched arms at their end, said pressure heads being interchangeable to wider size; and a fixing cuff around said pressure heads to stabilize said heads when affixed to a heart.
Claim 2
Dependent Claim
130 words
