    摘要： Systems and methods for generating blood flow with a blood pump including a membrane and an encapsulated actuator are described. The pump may be implantable and may include a stator assembly, an electromagnetic assembly supported by the stator assembly, a magnetic assembly, one or more springs attached to the stator and the magnetic assembly, and encapsulation portions that connect the magnetic assembly to the stator assembly. The magnetic assembly may further be coupled to a membrane assembly including a flexible membrane. The electromagnetic assembly may be selectively activated to cause the magnetic assembly to reciprocate, thereby causing the membrane assembly to reciprocate and inducing wavelike undulations in the flexible membrane to pump blood from an inlet to an outlet of the pump. The encapsulation portions may prevent blood from interacting with an interior moving portion of the pump thereby reducing the risk of hemolysis.

    摘要： Systems and methods for generating blood flow with a pump incorporating linear bearing technology are provided. The pump may include an actuator assembly, a moving assembly, and a linear hydrodynamic or thin-film bearing positioned within a housing. The moving assembly may include at least one magnet and the actuator assembly may include a magnetic assembly for selectively generating a magnetic field to cause linear reciprocating movement of the moving assembly with respect to the actuator assembly. The linear hydrodynamic or thin-film bearing may include a bearing portion on the moving assembly that is in fluid communication with a bearing portion on the actuator assembly or pump housing. The system may involve an implantable pump, an extracorporeal battery and a controller coupled to the implantable pump. The implantable pump may be suitable for use as a left ventricular assist device (LVAD).

    摘要： An implantable pump system is provided, suitable for use as a left ventricular assist device (LVAD) system, having an implantable 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 pump. The implantable pump includes a flexible membrane coupled to an actuator assembly that is magnetically engagable with electromagnetic coils, so that when the electromagnetic coils are energized, the actuator assembly causes wavelike undulations to propagate along the flexible membrane to propel blood from through the implantable pump. The controller may be programmed by a programmer to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while operating in an efficient manner that avoids thrombus formation, hemolysis and/or platelet activation.

    摘要： 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.
