A method for treating a treatment site within a body of a patient with a catheter system includes generating energy with an energy source; positioning an inflatable balloon substantially adjacent to the treatment site, the inflatable balloon having a balloon wall that defines a balloon interior that receives a balloon fluid; receiving energy from the energy source with an energy guide; guiding the energy with the energy guide into the balloon interior; sensing acoustic sound waves generated in the balloon fluid with an acoustic sensor that is positioned outside of the body of the patient; generating a sensor signal with the acoustic sensor based at least in part on the sensed acoustic sound waves; electrically coupling a system controller to the acoustic sensor; receiving the sensor signal from the acoustic sensor with the system controller; and controlling operation of the catheter system with the system controller based at least in part on the sensor signal, the system controller being configured to recognize one of: (i) normal operation of the catheter system, and (ii) potential damage to the energy guide.
