Abstract
An implantable medical device (“IMD”) is provided having an antenna and an RF telemetry module for far field telemetry communications arranged on an exterior of the IMD housing, such that telemetry signal processing may be performed on the exterior of the housing. One or more feedthrough conductive paths extend through the housing to communicatively couple the RF module to circuitry within the housing. In this manner RF module is arranged entirely external to the housing, such that only power and/or low frequency data bit signals are required to be passed through the feedthrough conductive path. This allows the feedthrough conductive path to be filtered to prevent undesired interference signals (e.g., electromagnetic interference (EMI) signals) from entering the housing through the feedthrough conductive path coupled to the RF module. In some embodiments, the antenna and RF module are formed in an integrated assembly attachable to an exterior portion of the housing.
