Abstract
A controller for an implantable blood pump, includes an accelerometer configured to measure at least one from the group consisting of position and movement of the controller. Processing circuitry is configured to control operation of the implantable blood pump, the processing circuitry being in communication with the accelerometer, the processing circuitry being configured to adjust a speed of the implantable blood pump if the measured at least one from the group consisting of position and movement deviates from a respective predetermined threshold.
