For the recanalization of occluded arteries by means of plaque ablation an electrical technique, called spark erosion, has been developed. In vitro tests have shown that well-defined holes can be produced easily in fibrous, collagenous and lipid plaques, with minimal thermal side effects. As the method is not, by its nature, selective in vivo application will require an additional guidance technique to avoid arterial perforation. For this purpose, the potential use of tissue impedance as a sensing parameter has been tested. Main advantages of spark erosion are that it is a well controllable, low cost and highly effective tissue ablation technique.
为了通过斑块消融来实现闭塞动脉的再通，已经开发出一种称为火花腐蚀的电技术。体外试验表明，在纤维性、胶原性和脂质斑块中能够轻松产生边界清晰的孔洞，且热副作用极小。由于该方法本质上不具有选择性，因此在体内应用时需要额外的引导技术以避免动脉穿孔。为此，已经对将组织阻抗作为传感参数的潜在用途进行了测试。火花腐蚀的主要优点在于它是一种易于控制、成本低廉且高效的组织消融技术。
