Systems and methods for an implantable medical device which utilizes a patch antenna for communicating with an external device. The implantable medical device includes a housing, a header, and a patch antenna formed using an RF plate and a ground plate, which may be or include a metal surface of the housing. Also, a material of the header forms a dielectric of the patch antenna.

Systems and methods for incorporating a patch antenna in an implantable medical device

A method for managing power during communication with an implantable medical device, including establishing a communications link, utilizing a power corresponding to a session start power, to initiate a current session between an implantable medical device (IMD) and external device. A telemetry break condition of the communications link is monitored during the current session. The power utilized by the IMD is adjusted between low and high power levels, during the current session based on the telemetry break condition. The number of sessions is counted, including the current session and one or more prior sessions, in which the IMD utilized the higher power level, and a level for the session start power to be utilized to initiate a next session following the current session is adaptively learned based on the counting of the number of sessions.
