A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve includes an energy source, a balloon, an energy guide, and an electrical analyzer assembly. The energy source generates energy. The balloon is positionable substantially adjacent to the treatment site. The balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The energy guide is configured to receive energy from the energy source and guide the energy into the balloon interior. The electrical analyzer assembly is configured to monitor a balloon condition during use of the catheter system. The electrical analyzer assembly can include a first electrode, a second electrode, and an impedance detector that is electrically coupled to the first electrode and the second electrode. The impedance detector is configured to detect impedance between the first electrode and the second electrode. |
