Abstract: A catheter includes a flexible tubing having a proximal end and a distal end. The catheter also includes an electrode assembly attached to the distal end of the flexible tubing and including a first magnet therein. The electrode assembly including an electrically conductive tip electrode and an electrically nonconductive coupler which is connected between the tip electrode and the distal end of the flexible tubing. The electrically conductive tip electrode comprises a hollow elongated tip electrode including a sidewall provided with one or more elongated gaps extending through the sidewall. The one or more elongated gaps providing flexibility in the sidewall for bending movement of the tip electrode relative to a longitudinal axis of the catheter body. The first magnet is responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.

Abstract: A flexible tip electrode for an ablation catheter and methods for making the same are disclosed. The electrode has a surface configuration that improves flexibility of the electrode. Also, the surface configuration may allow electrode lengthwise freedom of movement, such that the electrode may be shortened when pressed against the target tissue. A coil may be located in the electrode to bias the electrode toward a predetermined configuration.
Abstract translation: 公开了一种用于消融导管的柔性尖端电极及其制造方法。 电极具有改善电极柔性的表面构型。 此外，表面构造可以允许电极长度上的移动自由度，使得当按压目标组织时电极可能缩短。 线圈可以位于电极中，以将电极偏压到预定的构型。
