Abstract
An implantable medical device (IMD) system includes an IMD, a transceiver antenna lead for the IMD, and a wireless therapy delivery transponder or probe that is remotely activated by the IMD via the transceiver antenna lead. The IMD and the wireless probe communicate using wireless RF-based transponder techniques. The wireless probe includes a capacitor that is charged when the IMD emits an appropriate electromagnetic field from the transceiver antenna lead. The wireless probe delivers electrical therapy in the form of electrical pulses from the capacitor in response to RF activation signals emitted by the IMD via the transceiver antenna lead.
