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.

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.

Abstract: A medical device is configured to set a post-atrial time interval in response to an atrial event and generate an event time signal in response to a ventricular electrical signal crossing an R-wave sensing threshold during the post-atrial time interval. The device accumulates oversensing evidence in response to the event time signal and adjusts a ventricular sensing control parameter based on the accumulated oversensing evidence in some examples.
