An interventional catheter was designed that can induce controlled endoluminal tissue lesions by means of bipolar radio-frequency (RF) electrocoagulation under fluoroscopic guidance. The technique was used to obtain safe and reproducible percutaneous occlusion of the porcine cystic duct by reactive endoluminal scar formation. The new triple-lumen, 7-F, polyethylene catheter contains two insulated active wires and accommodates a 0.038-inch steerable guide wire, which facilitates insertion and placement of the active catheter tip under fluoroscopic control. The coagulation technique is relatively simple and requires only a small, portable bipolar RF generator and ammeter.
设计了一种介入导管，该导管可在荧光镜引导下通过双极射频（RF）电凝诱导可控的腔内组织损伤。该技术用于通过反应性腔内瘢痕形成实现猪胆囊管的安全且可重复的经皮闭塞。新型三腔、7-F聚乙烯导管包含两根绝缘的有源导线，并容纳一根0.038英寸的可操纵导丝，这有助于在荧光镜控制下插入并放置有源导管尖端。凝血技术相对简单，仅需要一个小型便携式双极射频发生器和电流表。
