Abstract: Magnetic guided ablation catheters and methods of manufacture are disclosed. In an exemplary embodiment, a catheter includes a unitary flexible tubing having a proximal end and a distal end. A plurality of magnets are positioned along an axis of the unitary flexible tubing, the plurality of magnets provided within the unitary flexible tubing. During operation, the plurality of magnets are responsive to an external magnetic field to selectively position and guide the catheter within a body of a patient.

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 having a first magnet therein. The electrode assembly further includes 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 coupler and the tip electrode are coupled by an interlocking connection. The catheter also includes a second magnet spaced from the electrode assembly along a longitudinal axis of the tubing. The first magnet and the second magnet are responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.
