    Abstract: Ablation probes can include one or more metalized ceramic components. A metalized ceramic component can include one or more traces for conducting electrical energy and/or for functioning as an antenna for emitting radiation during an ablation procedure. A shaft of an ablation probe may be formed of metalized ceramic to give the shaft strength and to provide an electrical insulator between traces formed on the shaft and other components of the probe. A tip of an ablation probe may also be formed of metalized ceramic.
