Title: IMPLANTABLE PUMP SYSTEM HAVING A COAXIAL VENTRICULAR CANNULA
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. The implantable cardiovascular pump may be programmed to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while avoiding thrombus formation, hemolysis and/or platelet activation.
