The invention provides a device for generating shock waves. The device may comprise an elongated tube and a conductive sheath circumferentially mounted around the elongated tube. The device may further comprise first and second insulated wires extending along the outer surface of the elongated tube. A portion of the first insulated wire is removed to form a first inner electrode, which is adjacentto a first side edge of the conductive sheath. A portion of the second insulated wire is removed to form a second inner electrode, which is adjacent to a second side edge of the conductive sheath. Responsive to a high voltage being applied across the first inner electrode and the second inner electrode, a first shock wave is created across the first side edge and the first inner electrode, and asecond shock wave is created across the second side edge and the second inner electrode. 本发明提供了一种用于产生冲击波的装置。该装置可以包括长形管和周向地安装在长形管周围的导电护套。该装置还可以包括沿着长形管的外表面延伸的第一和第二绝缘导线。去除第一绝缘导线的一部分以构成第一内部电极，该第一内部电极与导电护套的第一侧边缘相邻。去除第二绝缘导线的一部分以构成第二
