Embodiment Construction

[0054] 1. In vitro test of the device of the present invention

[0055] Isolated porcine hearts were prepared for analysis by filling with water via valves provided in the superior vena cava and pulmonary veins (see RV water supply and LV water supply in Figure 1), while pressure sensors were Positioned at the left subclavian artery and left pulmonary artery (see left ventricular pressure sensor and right ventricular pressure sensor in Figure 1). The remaining lumen to and from the heart is blocked. Water was supplied to the heart until the pressure detected at the pressure sensor indicated that the pressure achieved was similar to the pressure during normal heart function (approximately 80 mmHg). The heart prepared in this way is supported by support wires and contained relatively tightly within a polyethylene bag. The vinyl bag is a non-elastic material and represents the pericardium. A device according to the present invention comprising a balloon inserted through a hole...

Abstract

An apparatus for assisting ventricular contraction, the apparatus comprising a pressurizer and a driver, wherein the pressurizer is adapted to apply localized pressure to only the outer wall of one ventricle, or a portion thereof, and the A driver is operatively linked to the pressurizer so as to be able to drive cycles of increasing and decreasing pressure applied by the pressurizer. The invention also relates to a method of implanting said device and a method of treating pumping failure of a heart using said device.

Description

technical field [0001] The present invention relates to cardiac assist devices for assessing cardiac function, in particular to a method for assisting ventricular contractions. The invention also relates to a method in which the aforementioned apparatus can be used. Background technique [0002] In the heart of a healthy individual, the amount of blood pumped from the ventricles is usually optimal (ie, blood from the left ventricle to the aorta and from the aorta to the rest of the body, and blood from the right ventricle to pulmonary arteries and blood from the pulmonary arteries to the lungs). However, in many acute and chronic conditions, the ability of ventricular tissue to contract effectively is adversely affected, resulting in a decrease in the amount of blood that can be pumped from either or both ventricles (ie, the amount of blood that is maintained in each ventricle A drop in the fraction of the amount of blood that can be ejected during a systolic period; insuf...
