To provide a suitable lesion crossing shock wave catheter.SOLUTION: The present invention provides a catheter for treating an occlusion in a blood vessel. The catheter includes at least one electrode pair (222, 243) positioned inside a flexible angioplasty balloon (280) at a distal end (200) of the catheter. In some designs, the electrode pairs are arranged in a low-profile or co-planar configuration to reduce the diameter of the distal end of the device and allow treatment of tight, difficult-to-cross occlusions. The flexible angioplasty balloon (280) has an extremely low profile and does not need to be folded prior to insertion of the catheter into the cardiovascular system. During treatment, the balloon may be expanded by a relatively small amount sufficient to immerse the electrode pair in the conductive fluid prior to generating shock waves across the electrodes to treat the occlusion. The balloon may be made from a material having elastomeric properties such that when it is deflated following treatment, it returns to its original low-profile configuration.SELECTED DRAWING: Figure 2B
