Abstract: An intra-cardiac device component (ICDC) is inserted into one to four chambers of the heart. The ICDC in the right atrium and left atrium expands while the tricuspid and mitral valves are open during the first-time epoch. The expansion in the right atrium and left atrium pushes blood from these atriums into their respective ventricles. The ICDC in the right ventricle and left ventricle contracts at this time epoch and the pulmonary and aortic valves are closed. In the succeeding time epoch, the ICDC in the right atrium and left atrium contracts while the tricuspid and mitral valves are closed, and the right atrium and left atrium are filling with blood. The ICDC in the right ventricle and left ventricle expand in this time epoch while the pulmonary and aortic valves are open. This sequence increases blood flow into the pulmonary artery and aorta and helps to remedy the decreased ability to pump blood in heart failure patients.
