A heart simulator with a very detailed structure with a mechanism that causes the realistic movement of the human heartbeat. Intended for simulation and training of coronary aortic bypass and bypass grafting. The mechanism works like a real muscle and is programmable with different speeds and rhythms. The kit includes a controller, a compressor and a power supply (all of which are necessary for the functioning of a beating heart), as well as sewn and interchangeable
coronary artery sites for anastomosis training.
