Abstract
A method of managing multiple power sources for an implantable blood pump includes operating the implantable blood pump with both power from an internal battery, the internal battery being disposed within an implantable controller and in communication with the implantable blood pump, and with transcutaneous energy transfer system (TETS) power in communication with the implantable blood pump, if TETS power is available.
Claims20
A method of managing multiple power sources for an implantable blood pump, comprising:
- operating the implantable blood pump with both power from an internal battery and transcutaneous energy transfer system (TETS) power simultaneously, the internal battery being disposed within an implantable controller and in communication with the implantable blood pump, and the TETS in communication with the implantable blood pump.
A method of managing multiple power sources for an implantable blood pump, comprising:
- operating the implantable blood pump with both power from an internal battery and transcutaneous energy transfer system (TETS) power simultaneously, the internal battery being disposed within an implantable controller and in communication with the implantable blood pump, and the TETS in communication with the implantable blood pump, if during operation of the implantable blood pump:
- a minimum speed of the implantable blood pump is unable to be maintained by TETS power alone and an internal battery capacity is less than a predetermined reserve threshold;
- or
- a set speed of the implantable blood pump is unable to be maintained by TETS power alone and the internal battery capacity is greater than the predetermined reserve threshold.
A control circuit for an implantable blood pump, comprising:
- processing circuitry configured to:
- operate the implantable blood pump with both power from an internal battery and transcutaneous energy transfer system (TETS) power simultaneously, the internal battery being disposed within an implantable controller and in communication with the implantable blood pump, and the TETS in communication with the implantable blood pump, if TETS power is available and if battery only operation is not required.
A control circuit for an implantable blood pump, comprising:
- processing circuitry configured to:
- operate the implantable blood pump with both power from an internal battery and transcutaneous energy transfer system (TETS) power simultaneously, the internal battery being disposed within an implantable controller and in communication with the implantable blood pump, and the TETS in communication with the implantable blood pump, if during operation of the implantable blood pump:
- a minimum speed of the implantable blood pump is unable to be maintained by TETS power alone and an internal battery capacity is less than a predetermined reserve threshold;
- or
- a set speed of the implantable blood pump is unable to be maintained by TETS power alone and the internal battery capacity is greater than the predetermined reserve threshold.
