    Abstract: A catheter system (100) for treating a treatment site (106) within or adjacent to the vessel wall of a blood vessel (108), or the heart valve, includes an energy source (124), a balloon (104), an energy guide (122A), and a balloon integrity protection system (142). The energy source (124) generates energy. The balloon (104) is positionable substantially adjacent to the treatment site (106). The balloon (104) has a balloon wall (130) that defines a balloon interior (146). The balloon (104) is configured to retain a balloon fluid (132) within the balloon interior (146). The energy guide (122A) is configured to receive energy from the energy source (124) and guide the energy into the balloon interior (146) so that plasma is formed in the balloon fluid (132) within the balloon interior (146). The balloon integrity protection system (142) is operatively coupled to the balloon (104). The balloon integrity protection system (142) is configured to inhibit rupture of the balloon (104) due to the plasma formed in the balloon fluid (132) within the balloon interior (146) during use of the catheter system (100).

    Abstract: Medical devices and methods are disclosed in the present application. In one illustrative example a medical device may comprise a catheter shaft extending from a proximal end to a distal end and the catheter shaft may include a plurality of catheter shaft lumens extending through at least a portion of the catheter shaft. The device may further include a first balloon member defining a first lumen in fluid communication with a first one of the plurality of catheter shaft lumens and a second balloon member defining a second lumen in fluid communication with a second one of the plurality of catheter shaft lumens. In some embodiments, the second balloon member may be disposed around the first balloon member and comprise a plurality of ports and a first raised portion and a second raised portion.
