1. A method for softening and/or breaking calcifications on tissue comprising:

  • placing a balloon adjacent to calcified tissue, wherein the balloon has a longitudinal axis;

    inflating the balloon with a liquid;

    introducing a shock wave generator into the balloon at a first location, wherein the shock wave generator is arranged to produce a shock wave within the balloon to propagate through the liquid for impinging upon the calcified tissue, and wherein the shock wave generator is mounted on an elongate element that is slidably enclosed within an elongate tube;

    initiating a shock wave within the balloon from the first location;

    changing the position of the shock wave generator within the balloon to a second location that is axially and/or longitudinally displaced from the first location; and

    initiating a shock wave within the balloon from the second location to vary the shock wave impingement upon the calcified tissue.
