Abstract: Techniques for determining an attachment stability of leadless pacing device (LPD) implanted within a patient are described. For example, the LPD may detect one or more stability metrics from one or more electrodes of the LPD and/or an activity sensor within the LPD. Based on one or more of these stability metrics, e.g., a mechanical motion of the LPD, a stability module within the LPD may determine the attachment stability of the LPD within the patient. If the attachment stability is insufficient to provide efficacious therapy or indicates at least partial dislodgement of the LPD from tissue, the LPD may wirelessly transmit stability information to an external device. In some examples, the LPD may be implanted within a chamber of the heart.

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 circuity 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.

Abstract: According to one or more embodiments, a system is provided. The system includes a power device implantable within a patient for powering an implantable medical device. The power device includes a first coil configured to receive wireless power signals for powering the implantable medical device and processing circuitry configured to determine at least one measurable electrical characteristic in a plurality of electrical pathways in the power device including an electrical pathway to the first coil, and detect reduced performance in receiving wireless power signals based at least in part on the determined at least one measurable electrical characteristic.

Abstract: Various embodiments of a transcutaneous energy transfer system are disclosed. The system includes an internal component adapted to be disposed within a body of a patient and an external component adapted to be disposed outside the body of the patient. The external component includes an external controller that is adapted to determine whether an internal coil of the internal component is electromagnetically disconnected from an external coil of the external component. If electromagnetically disconnected, then the external controller is adapted to determine a reconnection time threshold based upon at least one of a power transfer efficiency value between the internal coil and the external coil, a charge state of an internal power source, or a power consumption value of an implantable device, and output a charging alarm if a time interval when the internal coil is electromagnetically disconnected from the external coil exceeds the reconnection time threshold.
