  • Computer-controlled tissue-based simulator for training in cardiac surgical techniques
    Patent number: 7798815
    Abstract: The present invention is directed to an electromechanical pumping system for simulating the beating of heart in a cardiac surgery training environment. A computer-controllable linear actuator is used to control the electromechanical pumping system. In a preferred embodiment, the electromechanical pumping system is linked to a porcine heart. The heart is made to beat by inserting intra-ventricular balloons placed inside the heart and connected to the pumping system. When controlled by the electromechanical pumping system, the porcine heart is able to display normal and abnormal beating rhythms, as well as ventricular fibrillation. In addition, an electronic pressure sensor incorporated into the pumping system can be used to trigger a ventricular fibrillation mode when the porcine heart attached to the pumping system is handled by a trainee surgeon.
