1. A method for treating calcified lesions in vessels of a patient comprising:
advancing a device for generating shock waves into a vessel of the patient, the device comprising:
an elongated tube;
a member sealed to a distal end of the elongated tube that is fillable with a conductive fluid, and
a shock wave generation station within the member, the shock wave generation station comprising:
a conductive sheath circumferentially mounted around the elongated tube, and
at least two wires passing at least partially through the conductive sheath between an outer surface of the elongated tube and an inner surface of the conductive sheath, each wire having an exposed portion defining an electrode that is spaced apart from the conductive sheath by a gap, wherein the electrodes defined by the at least two wires are located adjacent the same end of the conductive sheath;
applying a high voltage across the wires to cause current to flow between each electrode and the conductive sheath to create a separate shock wave at each gap; and
removing the device from the vessel of the patient.
