Shockwave Catheter System With Energy Control

Patent No. EP3861942 (titled "Shockwave Catheter System With Energy Control") was filed by Shockwave Medical on Sep 12, 2013. The application was issued on Mar 25, 2026.

Patent Summary

A system for treating calcified lesions comprises a catheter with an elongated carrier, a sealed balloon configured to receive a liquid, and first and second electrodes positioned within the balloon. A power source, comprising a capacitor and a switch, delivers voltage pulses to the electrodes by closing the switch to discharge the capacitor. Each pulse generates an electrical arc in the liquid, creating a steam bubble and a corresponding expansion shock wave. The power source senses the current flowing across the electrodes during each pulse and terminates delivery by opening the switch once the current reaches a predetermined limit. This limit ensures arc creation while preventing excessive capacitor discharge, thereby conserving electrode material and reducing unnecessary tissue heating.
