  • Patent number: 8827910
    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.

  • Patent number: 8187267
    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.
