Benefits of technology

"The invention is a device for treating cardiac disease by applying a highly compliant and elastic device to the external surface of the heart. The device can resist dilatation of the heart, provide acute wall support, and enhance reduction in the size of the heart using stored potential energy, without interfering with systolic contraction. The device has a compliance greater than a normal myocardium and is made from a biocompatible material. The device can be sized to cover both ventricles, one ventricle, ventricles and atria, or as a patch covering a portion of a chamber. The method includes surgically accessing the heart and applying the cardiac support device."

Problems solved by technology

In time, the heart becomes so enlarged the heart cannot adequately supply blood.
An afflicted patient is fatigued, unable to perform even simple exerting tasks and experiences pain and discomfort.
Further, as the heart enlarges, the internal heart valves may not adequately close.
This may impair the function of the valves and further reduce the heart's ability to supply blood.
Importantly, there is no cure for congestive heart disease.

Embodiment Construction

A. Congestive Heart Disease

[0030] With initial reference to FIGS. 1 and 1A, a normal, healthy human heart H′ is schematically shown in cross-section and will now be described in order to facilitate an understanding of the present invention. In FIG. 1, the heart H′ is shown during systole (i.e., high left ventricular pressure during the ejection phase). In FIG. 1A, the heart H′ is shown during diastole (i.e., low left ventricular pressure during the relaxation phase).

[0031] The heart H′ is a muscle having an outer wall or myocardium MYO′ and an internal wall or septum S′. The myocardium MYO′, septum S′ and valve plane VP′ define four internal heart chambers, including a right atrium RA′, a left atrium LA′, a right ventricle RV′ and a left ventricle LV′. The heart H′ has a length measured along a longitudinal axis AA′-BB′ from an upper end or base B′ to a lower end or apex A′.

[0032] The heart H′ can be visualized as having an upper portion UP′ and a lower portion LP′, separated by t...

Abstract

A highly compliant and elastic cardiac support device is provided. The device is constructed from a biocompatible material is applied to an external surface of a heart. The device can be used to resist dilatation of the heart, to provide acute wall support, or to enhance reduction in the size of the heart using stored potential energy, without interfering with systolic contraction.

Description

BACKGROUND OF THE INVENTION [0001] Congestive heart disease is a progressive and debilitating illness characterized by a progressive enlargement of the heart. As the heart enlarges, the heart must perform an increasing amount of work to pump blood each heartbeat needed for metabolism. In time, the heart becomes so enlarged the heart cannot adequately supply blood. An afflicted patient is fatigued, unable to perform even simple exerting tasks and experiences pain and discomfort. Further, as the heart enlarges, the internal heart valves may not adequately close. This may impair the function of the valves and further reduce the heart's ability to supply blood. Importantly, there is no cure for congestive heart disease. [0002] Congestive heart failure has an enormous societal impact. In the United States alone, about five million people suffer from the disease. Alarmingly, congestive heart failure is one of the most rapidly accelerating diseases (about 400,000 new patients in the United...
