摘要： An ablation catheter includes a flexible elongated shaft having a flexible electrode at its distal end. The flexible electrode includes an inner, flexible, electrically-conductive element and an outer, flexible, electrically-conductive polymer layer in electrical contact with the inner, flexible, electrically-conductive element. The catheter further includes an electrically insulative sheath surrounding at least a portion of the flexible electrode and a linear displacement mechanism capable of adjusting at least one of the electrically insulative sheath and the flexible electrode to vary a length of the flexible electrode exposed at the distal end of the shaft. Also disclosed is an adjustable length ablation electrode and methods of ablating tissue.

摘要翻译： 消融导管包括在其远端具有柔性电极的柔性细长轴。 柔性电极包括内部柔性导电元件和与内部柔性导电元件电接触的外部柔性导电聚合物层。 所述导管还包括围绕所述柔性电极的至少一部分的电绝缘护套和能够调节所述电绝缘护套和所述柔性电极中的至少一个的线性位移机构，以改变在所述远端暴露的所述柔性电极的长度 的轴。 还公开了可调节长度的消融电极和消融组织的方法。
