Abstract: In an example, an implantable medical device (IMD) includes a hold capacitor configured to deliver an electrical therapy pulse, and charge pump circuitry configured to transfer energy from the battery to the hold capacitor. In this example, the charge pump circuitry comprises a plurality of capacitors, and switching circuitry configured to put the charge pump circuitry into a K-factor mode selected from a group of K-factor modes by opening and closing a combination of switches connected to the plurality of capacitors.

Abstract: A medical system is configured to deliver an implantable medical device to a targeted implant site. The system may include a processor configured to receive a cardiac electrical signal and determine a feature of the cardiac electrical signal. The processor may be configured to determine a position of the delivery tool based on at least one feature of the cardiac electrical signal. The processor may detect a deployment position of the delivery tool in response to the cardiac electrical signal feature meeting criteria for detecting the deployment position.

Abstract: Examples are described for configuring cardiac pacing circuitry of an implantable medical device. Circuitry that is configurable to control delivery of therapy or sense signals in accordance with a plurality of vectors may determine that one or more pins, for therapy delivery or sensing in accordance with a first subset of vectors of the plurality of vectors, are in an electrically floating state. Circuitry may selectively close one or more switches to couple at least a subset of the one or more pins to one or more set voltage levels, and deliver therapy in accordance with a vector of a second subset of vectors of the plurality of vectors, wherein the second subset of vectors is different than the first subset of vectors.
