    • A catheter system (100) for treating a treatment site (106) includes an energy source (124), an inflatable balloon (104), an energy guide (122A), and a pressure sensor (258, 358). The inflatable balloon (104) is positionable substantially adjacent to the treatment site (106). The inflatable balloon (104) has a balloon wall (130) that defines a balloon interior (146) that receives a balloon fluid (132). The energy source (124) generates energy that is received by the energy guide (122 A) so that the energy guide (122A) can guide the energy into a balloon interior (146). The pressure sensor (258, 358) senses a balloon pressure of the balloon fluid (132). A method for disrupting calcification at the treatment site (106) includes the steps of generating energy with the energy source (124), positioning the inflatable balloon (104) substantially adjacent to the treatment site (106), the inflatable balloon (104) having the balloon wall (130) that defines the balloon interior (146), the balloon interior (146) being configured to receive the balloon fluid (132), receiving energy from the energy source (124) with the energy guide (122A), guiding the energy from the energy source (124) into the balloon interior (146) with the energy guide (122 A); and sensing a balloon pressure of the balloon fluid (132) with a pressure sensor (258, 358).
