Abstract
A method of providing a pumping system for assisting a human patient's heart and providing a blood pump to be disposed outside the patient's body is disclosed. The blood pump has an inlet and an outlet. An inlet cannula is provided for insertion percutaneously into the vascular system of the patient, and is adapted to be placed in fluid communication with the blood pump inlet to provide blood to the blood pump. An outlet perfusion cannula is provided for insertion percutaneously into the vascular system of the patient, and is adapted to be placed in fluid communication with the blood pump outlet to provide blood to the patient's vascular system. The blood pump includes a control system to control the blood pump. The control system includes at least two control units for redundant control of the blood pump, and each control unit includes a watchdog for monitoring the control unit.
