Low loss band pass filter for RF distance telemetry pin antennas of active implantable medical devices
Abstract:
A hermetic terminal for an active implantable medical device (AIMD), includes an RF distance telemetry pin antenna, a capacitor conductively coupled between the antenna and a ground for the AIMD, and an inductor electrically disposed in parallel with the capacitor and conductively coupled between the antenna and a ground for the AIMD. The capacitor and the inductor form a band pass filter for attenuating electromagnetic signals through the antenna except at a selected frequency band. Values of capacitance and inductance are selected such that the band pass filter is resonant at the selected frequency band. In an alternative form, the band pass filter is coupled in series with the telemetry pin antenna for attenuating MRI signals of a selected frequency band.
