1. An intravascular valvuloplasty method for breaking calcium deposits on a leaflet of an aortic valve, the leaflet being connected to the wall of the aorta and having inferior and superior concave regions, said method comprising:

  • advancing a catheter into the region of the aortic valve, said catheter carrying a tubular member formed from a non-compliant material that is fillable with a fluid, said tubular member carrying a shock wave generator having a pair of electrodes within the tubular member, the electrode pair for producing a plurality of high voltage pulses to generate electric arcs that create shock waves that propagate through the liquid and through the tubular member;

    advancing the tubular member so that a portion thereof fits within the superior concave region of a leaflet between the leaflet and the wall; and

    energizing the shock wave generator to produce a shock wave that propagates through the liquid for impinging upon the valve leaflet in order to break calcium deposits on the leaflet.
