Heart pump system in heart-coronary artery-myocardial bridge circulation apparatus

The cardiac muscles that cover the surface of the coronary artery are called Myocardial Bridge. But so far many research methods on the myocardial bridge are involved with clinical patients or animals, so they have some limitations (e.g. systematicless, difficulties in measuring the flow of the coronary artery and so on). Designing a heart-coronary artery-myocardial bridge circulation system model provides a good approach to solve above problems. But documents on this subject seldom have been reported until now. The heart pump is the key part of the whole simulation system. It can simulate the waveform of the pressure and adjust the flow and the frequency in our experiments. Successfully developing the heart pump produces an alternative experimental method to go further into other problems of the circulation system.
