Described herein are external devices, and methods for use therewith, that are configured to communicate with one or more implantable medical devices (IMDs) implanted within a patient using conductive communication, wherein the external device includes or is communicatively coupled to at least three external electrodes that are in contact with the patient. Certain such methods involve the external device identifying, for each IMD, of the plurality of IMDs, which one of the plurality of communication vectors is a preferred communication vector for communicating with the IMD, based on respective indicators of conductive communication quality that are determined for the plurality of communication vectors. Certain embodiments involve determining when there should be a reassessment of which one of the plurality of communication vectors is the preferred communication vector for communicating with an IMD, and in response thereto, identifying an updated preferred communication vector for communicating with the IMD.

Devices, systems and methods for improving conductive communication between external devices and implantable medical devices

An implantable system includes an implantable medical device (IMD) and a non-transvenous lead that is configured to be implanted outside of a heart. The IMD includes an output configured to be connected at least to the lead, a current generator (CG) circuit configured to generate pacing pulses, a switching circuit coupled between the CG circuit and the output, one or more capacitors coupled in parallel with the CG circuit and the switching circuit, and a control circuit coupled to the CG circuit. The control circuit is configured to manage the CG circuit to generate the pacing pulses with a constant current at the output.
