Heart Pump System in Heart-Mural coronary artery-Myocardial Bridge Simulative Device

The myocardial tissue covering the artery is termed a myocardial bridge. But so far many researches on the myocardial bridge have been involved with clinical patients or animals, which have some limitations (e.g. lack of systematicness, difficulties in measuring the flow in the mural coronary artery and so on). Designing a Heart-Mural coronary artery-Myocardial Bridge Simulative Device provides a good approach to solve above problems; however, documents on this subject have seldom been reported until now. The heart pump as the key part of the whole simulative device should be able to simulate the waveform of blood pressure, adjust blood flow and regulate heart rate. Our experimental results basically met above requirements. The heart pump proposed in the paper presented an alternative experimental method to go further into other issues about the cardiovascular circulation system.
