Abstract

The invention is about a permanent total artificial heart device that is developed for the patients who are at the end-stage heart failure and included in the heart transplantation program, and which is placed into the ventricles of the patient's heart completely or placed surgically into the space obtained when a piece of ventricle is removed. The device employs “direct drive technology,” technically using the advantages of brushless electric motors. Special-designed engines require quite little energy for the pulsatile blood flow produced by stopping and starting synchronously with the ECG signals. It is about a permanent total artificial heart device system that will offer high quality of life for many years to the patients as it protects the heart valves and heart conduction system, has wireless charging and longer battery life.

Claims24

Dependent claims

A total artificial heart device for patients with end-stage heart failure and insolvent heart patients, comprising at least two blood pump motors that run synchronously with a sinus rhythm of a sinus node of a heart of a patient and can be controlled individually;

wherein one of the blood pump motors is a left ventricle blood pump motor, and the other is a right ventricle blood pump motor;
wherein the left ventricular blood pump motor maintains microcirculation by pushing blood from the right atrium into a pulmonary artery direction;
wherein the right ventricular blood pump motor maintains systemic circulation by pushing blood from the left atrium into an aorta direction;
wherein the total artificial heart device is configured to be placed into a heart membrane of the heart by removing left and right ventricles of the heart surgically, and alone provides a blood flow required for the patient;
wherein the total artificial heart device further comprises an internal control unit, which comprises a microprocessor that controls the left ventricular blood pump motor and the right ventricle blood pump motor synchronously to keep aorta blood flow rate and pulmonary arterial blood flow rate constantly equal in real time and uninterrupted;
wherein the total artificial heart device further comprises a first annular spacer and a second annular spacer, an upper end of the left ventricular blood pump motor is installed to the first annular spacer, and an upper end of the right ventricular blood pump motor is installed to the second annular spacer.
