Abstract
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).
