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.

Method for minimizing misalignment notifications for a transcutaneous energy transfer system

A method comprises identifying P-waves within a cardiac signal stored by a medical device for a cardiac episode detected by the medical device, and calculating a gain factor for display of the cardiac signal based on the identified P-waves.

Electrocardiogram gain adjustment

A system and method for detecting and verifying bradycardia/asystole episodes includes sensing an electrogram (EGM) signal. The EGM signal is compared to a primary threshold to sense events in the EGM signal, and at least one of a bradycardia or an asystole is detected based on the comparison. In response to detecting at least one of a bradycardia or an asystole, the EGM signal is compared to a secondary threshold to sense events under-sensed by the primary threshold. The validity of the bradycardia or the asystole is determined based on the detected under-sensed events.

Method and apparatus for verifying bradycardia/asystole episodes via detection of under-sensed events

A controller implantable within the body of a patient as part of a left ventricular assist device (LVAD) system and a method therefore are provided. According to one aspect, the controller includes processing circuitry configured to receive inputs from at least one of: at least one internal component of the LVAD system, at least one external component of the LVAD system, and at least one clinician's device, and determine a charging rate for charging a battery of the LVAD system internal to the patient based on at least one of the received inputs.
