Abstract: Disclosed herein, among other things, are methods and apparatus related to ablation catheter systems with wireless temperature sensing. The present subject matter provides an ablation catheter system including an ablation catheter configured to ablate a target zone of tissue and at least one temperature sensitive resonator coupled to the ablation catheter. The resonator is configured to wirelessly emit a signal indicative of a sensed temperature in response to an interrogation signal. The ablation catheter system also includes an external device configured to provide the interrogation signal and to receive and decode the emitted signal from the resonator. The temperature sensitive resonator is configured to be placed proximate to and in thermal conduction with the target zone of tissue and to resonate at a frequency dependent upon a temperature of the resonator when excited by the interrogation signal, in various embodiments.
