Abstract: A system for minimizing misalignment notifications for a TETS having an implantable blood pump, an external controller having a power source and a processing circuitry, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and the implantable blood pump. The implantable controller having a power source configured to receive power from the receiving coil. The processing circuitry may be configured to: operate in a first mode where an alert is generated when a power efficiency transfer between the transmission coil and the receiving coil is below a first predetermined threshold; and operate in a second mode where the alert is only generated when the power remaining in the power source for the implantable controller is below a first predetermined power source threshold.
