Abstract: An implantable medical device has a therapy module configured to generate a composite pacing pulse including a series of at least two individual pulses. The therapy module is configured to generate the composite pacing pulse by generating a first pulse of the at least two individual pulses by selectively coupling a first portion of a plurality of capacitors to an output signal line and generate a second pulse of the at least two individual pulses by selectively coupling a second portion of the plurality of capacitors to the output signal line.

Abstract: An extra-cardiovascular implantable cardioverter defibrillator (ICD) having a low voltage therapy module and a high voltage therapy module is configured to select, by a control module of the ICD, a pacing output configuration from at least a low-voltage pacing output configuration of the low voltage therapy module and a high-voltage pacing output configuration of the high voltage therapy module. The high voltage therapy module includes a high voltage capacitor having a first capacitance and the low voltage therapy module includes a plurality of low voltage capacitors each having up to a second capacitance that is less than the first capacitance. The ICD control module controls a respective one of the low voltage therapy module or the high voltage therapy module to deliver extra-cardiovascular pacing pulses in the selected pacing output configuration via extra-cardiovascular electrodes coupled to the ICD.

Abstract: An extra-cardiovascular implantable cardioverter defibrillator (ICD) is configured to induce a tachyarrhythmia by charging a high voltage capacitor to a voltage amplitude and delivering a series of pulses to a patient's heart by discharging the capacitor via an extra-cardiovascular electrode vector. Delivering the series of pulses includes recharging the high-voltage capacitor during an inter-pulse interval between consecutive pulses of the series of pulses.

Abstract: This disclosure is directed to techniques for delivering cardiac pacing pulses to a patient's heart by a cardiac system, such as an extra-cardiovascular ICD system. An ICD operating according to the techniques disclosed herein delivers cardiac pacing pulses using high-voltage therapy circuitry typically configured for delivering high-voltage cardioversion/defibrillation shocks. The ICD delivers the high-voltage pacing therapy via extra-cardiovascular electrodes, such as one or more extra-cardiovascular electrodes carried by a medical electrical lead extending from the ICD and/or the housing of the ICD.

Abstract: Techniques for facilitating improved power management for an implantable device are provided. In one example, an implantable device includes a telemetry circuit and a power management circuit. The telemetry circuit is configured to facilitate a telemetry session between the implantable device and an external device. The power management circuit is configured to connect a power supply to the telemetry circuit via a first current-limiting device based on a determination that the telemetry circuit satisfies a defined criterion. The power management circuit is also configured to connect the telemetry circuit to a second current-limiting device based on a determination that the telemetry circuit is connected to the first current-limiting device for a defined period of time.
