Zusammenfassung:Various embodiments of the systems, methods and devices are provided for breaking up calcified lesions in an anatomical conduit. More specifically, an electrical arc is generated between two spaced-apart electrodes disposed within a fluid-filled balloon, creating a subsonic pressure wave. In some embodiments, the electrodes comprise a plurality of points or extensions that allow the electrical arc to form at any one of the plurality of points to, among other things, extend the electrode life.
