Abstract
An implantable electrode catheter device comprising an inner electrode catheter and an outer electrode catheter. The outer electrode catheter including a catheter shaft having at least one electrode at a distal end and a lumen to receive the inner electrode catheter therein. The outer electrode is adjustable or movable relative to the inner electrode catheter in an axial direction. The inner electrode catheter has a fixation element disposed at a distal end. The inner electrode catheter together with the fixation element forms an indifferent electrode whereby radio frequency catheter ablation occurs between the electrode and the indifferent electrode.
Claims16
An implantable electrode catheter device comprising:
- an inner electrode catheter;
- and
- an outer electrode catheter, the outer electrode catheter comprising:
- a catheter shaft having at least one electrode pole located at a distal end;
- and
- a lumen which can receive the inner electrode catheter therein, the outer electrode catheter is adjustable or movable relative to the inner electrode catheter in an axial direction, wherein the inner electrode catheter is provided with a stylet and has a fixation element disposed at the distal end, the inner electrode catheter together with the fixation element forms an indifferent electrode pole whereby radio frequency catheter ablation occurs between the electrode pole of the outer electrode catheter and the indifferent electrode pole.
A method for treatment of creating an ablation path, the method comprising:
- guiding an inner electrode catheter trans-septal by means of a steerable guiding catheter to a desired target in the left atrium of a patient, wherein the inner electrode catheter has an electrically conducting coil;
- fixing the distal end of the inner electrode catheter at the inner wall of the left atrium with a helical screw by the aid of a stylet having a flattened tip or with a magnet such that the electrically conducting coil of the inner electrode catheter and the helical screw form an indifferent electrode pole;
- retracting the guiding catheter and the stylet having a flattened tip,
- guiding an outer electrode catheter over the inner electrode catheter such that the outer electrode catheter concentrically encases the inner electrode catheter, wherein a shaft of the outer electrode catheter includes an electrode pole;
- inserting the appropriate special formed stylet;
- and
- applying a high frequency voltage between the electrode pole of the outer electrode catheter and the indifferent electrode pole thereby heating subjacent tissue and creating an ablation path.
