Electrical analyzer assembly for intravascular lithotripsy device

A method for treating a treatment site within or adjacent to a vessel wall or heart valve within a body of a patient, the method comprising steps of:

• generating energy with an energy source;
• positioning a balloon substantially adjacent to the treatment site, the balloon having a balloon wall that defines a balloon interior that receives a balloon fluid;
• directing the balloon fluid into the balloon interior through an inflation conduit;
• receiving energy from the energy source with an energy guide;
• guiding the energy with the energy guide into the balloon interior;
• monitoring a condition of the balloon with an electrical analyzer assembly while energy is being guided into the balloon interior, the electrical analyzer assembly including (i) a first electrode that is positioned within the inflation conduit, (ii) a second electrode, and (iii) an impedance detector that is electrically coupled to the first electrode and the second electrode;
• and
• detecting an impedance between the first electrode and the second electrode with the impedance detector.
