Abstract
For the recanalization of arteries obstructed by atherosclerotic plaques an electrical technique, called spark erosion, has been developed. A 500-kHz, square-wave, 700-V (effective value) voltage is applied between a small 1-2-mm-diameter electrode and atherosclerotic tissue for short periods of 0. 6-10 ms. In vitro tests have shown that well-defined holes can be produced easily in fibrous, collagenous and lipid plaques, with minimal thermal side effects. The results show that spark erosion is an easily controlled, low-cost and highly effective tissue ablation technique.
