A recently granted patent (Publication Number: US11950793B2) discloses a catheter designed for treating occlusions in blood vessels. The catheter comprises a tubular inner member with an emitter assembly that includes two insulated wires with uninsulated distal faces, a conductive sheath, and spark gaps. A flexible member attached to the distal end of the catheter can be filled with conductive fluid to generate shock waves when an electrical pulse is applied across the wires. The catheter also includes features such as insulating sheaths, fluid pump, fluid return line, pressure relief valve, and secondary conductive sheaths for enhanced functionality.

The method outlined in the patent involves introducing the catheter into a patient's vasculature, aligning the distal end with the treatment region, filling the flexible member with conductive fluid, and initiating shock waves by applying an electrical pulse across the wires. The method aims to effectively treat occlusions in blood vessels using the unique design of the catheter. The patent also specifies variations in the catheter design, such as the circumferential offset of the insulated wires and the inclusion of additional insulated wires and spark gaps for more targeted treatment. Overall, the patented catheter and method offer a novel approach to addressing occlusions in blood vessels with the potential for improved patient outcomes.
