Abstract: An implantable cardiovascular blood pump system is provided, suitable for use as a left ventricular assist device (LVAD) system, having an implantable cardiovascular pump, an extracorporeal battery and a controller coupled to the implantable pump, and a programmer selectively periodically coupled to the controller to configure and adjust operating parameters of the implantable cardiovascular pump. The implantable cardiovascular blood pump includes a coaxial inflow cannula and outflow cannula in fluid communication with one another and with a pumping mechanism. The pumping mechanism may be a vibrating membrane pump which may include a flexible membrane coupled to an electromagnetic actuator assembly that causes wavelike undulations to propagate along the flexible membrane to propel blood through the implantable cardiovascular pump.
