摘要： A heart pump including a housing forming a cavity including at least one inlet and at least one outlet, an impeller provided within the cavity, the impeller including vanes for urging fluid from the inlet to the outlet upon rotation of the impeller, a drive that rotates the impeller within the cavity, a magnetic bearing including at least one bearing coil that controls an axial position of the impeller within the cavity and a controller. The controller includes an electronic processing device that monitors changes in a bearing indicator in response to a perturbation in blood flow, the bearing indicator being at least partially indicative of operation of the magnetic bearing and controls the drive to thereby selectively change a rotational speed of the impeller at least partially in accordance with changes in the bearing indicator.

摘要： An implantable blood pump includes motor control circuitry and power electronics circuitry integrated within the implantable pump body. The motor control circuitry and power electronics circuitry is configured to energize and control motor windings to rotate the pump rotor and impeller. Additional control circuitry and power electronics circuitry may be integrated within the pump housing to energize and control magnetic bearings of a magnetic levitation pump. A percutaneous cable coupled between the implantable blood pump and an extracorporeal monitor includes a reduced number of leads to provide power and control signals to the implantable blood pump. Wireless communication between the extracorporeal monitor and the integrated power electronics and control circuitry facilitates the use of a percutaneous cable with as few as two leads for providing power to the implantable pump.

摘要： An impeller and rotor structure for a magnetically levitated pump define a smooth primary flow path and U-shaped secondary flow path, which extends around an annular magnetic rotor. The u-shaped secondary flow path is defined by a large outer side gap along an outer surface of the rotor, a large bottom gap along a bottom surface of the rotor and a large inner gap along an inner surface of the rotor. Shroudless impeller blades are purely radial and overhung from a thin peripheral ring attached to the annular magnetic rotor. A center post having a low aspect ratio extends through the annular rotor. The low aspect ratio is configured to prevent flow in the primary flow path from colliding directly with flow in the secondary flow path at the inner radial gap.

摘要： A controller for a heart pump, the controller including a processing system for determining movement of an impeller within a cavity in a first axial direction, the cavity including at least one inlet and at least one outlet, and the impeller including vanes for urging fluid from the inlet to the outlet, causing a magnetic bearing to move the impeller in a second axial direction opposite the first axial direction, the magnetic bearing including at least one coil for controlling an axial position of the impeller within the cavity, determining an indicator indicative of the power used by the magnetic bearing and causing the magnetic bearing to control the axial position of the impeller in accordance with the indicator to thereby control a fluid flow between the inlet and the outlet.

摘要： The present invention generally relates to ventricular assist device power monitoring and conservation. In some embodiments, a pump controller may transition the pump to operate in a power-saving operational mode when a power source and/or a power source condition indicate a need to conserve power. In some embodiments, when the power source is an emergency battery and when the emergency battery has powered the pump for an extended period of time, the controller may signal the pump to operate in the power saving-operational mode. In some embodiments, when a low power hazard condition is triggered by signals from one or more external power sources, the controller may signal the pump to transition to the power-saving operational mode if the condition lasts for an extended period of time. In some embodiments, the controller may trigger the power-saving mode when the emergency backup battery is below a voltage threshold.
