    Abstract: A medical device comprises a sensing circuit configured to sense at least one cardiac electrical signal, sense first ventricular event signals from the at least one cardiac electrical signal according to a sensitivity setting set to a first amplitude; and a control circuit in communication with the sensing circuit, the control circuit configured to determine that the at least one cardiac electrical signal meets suspected undersensing criteria, in response to determining that the suspected undersensing criteria are met, perform a morphology analysis of a first cardiac signal segment acquired from a first cardiac electrical signal of the at least one cardiac electrical signal sensed by the sensing circuit over a first predetermined time interval, determine that the first cardiac signal segment is a first tachyarrhythmia segment based on the morphology analysis, and adjust the sensitivity setting from the first amplitude to a second amplitude less than the first amplitude in response to determining that the first cardiac signal segment is a first tachyarrhythmia segment.

    Abstract: Devices, systems, and techniques are disclosed for determining spatial relationships between electrodes implanted within a patient. In one example, a medical device delivers, via a first electrode, an electrical stimulus and senses, for each other electrode, a respective electrical signal indicative of the electrical stimulus. The medical device determines, for each other electrode, a respective value for each respective electrical signal. The medical device determines, based on the respective values for each respective electrical signal and values of tissue conductivity of tissues of the patient interposed between the first electrode and the other electrodes, spatial relationships between the first electrode and each other electrode of the plurality of electrodes.

    Abstract: Devices, systems, and methods for more efficiently ablating tissue with pulsed field ablation energy while minimizing collateral injury to non-target tissue. In one embodiment, a system for ablating tissue at a treatment site comprises: an energy delivery device; and a control unit including: a source of impedance-modifying fluid in fluid communication with the energy delivery device; an energy generator in electrical communication with the energy delivery device, the energy generator being configured to transmit energy to the energy delivery device and the energy delivery device being configured to deliver energy to the treatment site; and processing circuitry configured to control delivery of the impedance-modifying fluid from the energy delivery device to the treatment site. In one embodiment, a method for ablating tissue comprises delivering an impedance-modifying fluid to a treatment site and delivering pulsed field ablation energy to the treatment site.

    Abstract: A TETS having an external controller having a power source, 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 an implantable blood pump. The implantable controller has a battery configured to receive power from the receiving coil and the external controller is configured to categorize power transfer states based on predetermined thresholds of efficiency and power demand, and user display states (associated with optional configurable notifications) based on the power transfer states and predetermined temperature thresholds of the transmission coil.
