Abstract: The present invention provides a catheter for treating occlusions in body lumens. The catheter includes a catheter body that is fillable with fluid. An impactor is connected to the distal end of the catheter body and has a proximal end inside the catheter body and a distal end outside the catheter body. The catheter also includes a shock wave source configured to generate a shock wave, and a deflector coupled to the proximal end of the impactor in between the shock wave source and distal end of the catheter body. When the shock wave source generates a shock wave, the shock wave impinges on the deflector causing the deflector to advance in a forward direction in conjunction with the impactor such that the distal end of the impactor delivers a mechanical force to the occlusion to restore flow to the body lumen.

Abstract: The present invention provides a catheter for treating occlusions in blood vessels. The catheter includes at least one electrode pair positioned inside of a flexible angioplasty balloon at the distal end of the catheter. In some designs, the electrode pairs are arranged in a low-profile or coplanar configuration, reducing the diameter of the distal end of the device and permitting treatment of tight and hard-to-cross occlusions. The flexible angioplasty balloon has an extremely low profile and does need to be folded before insertion of the catheter into the cardiovascular system. During treatment, the balloon can be expanded a relatively small amount sufficient to immerse the electrode pairs in a conductive fluid before generating shock waves across the electrodes to treat the occlusion. The balloon can be made of material having elastomeric properties such that it returns to its original low profile configuration when it is deflated following treatment.
