Abstract

The invention relates to a multi-pole esophageal electrode catheter that can be used for monitoring, pacing, and cardioversion of atrial fibrillation of the heart, the catheter having a flexible shaft (15) having a proximal end and a distal end and a multipolar electrode (3), characterized in that the distal end of the catheter is formed as a side arranged inflatable balloon (4) so that the multi-pole electrode (3) is aligned in the direction of the heart wall is constantly by means of the balloon.

Claims

1. Multi-pole oesophageal electrode catheter device which can be used for monitoring, stimulation and cardioversion of the heart, when treating atrial fibrillation of the heart, whereby the catheter comprises:

a flexible shaft with a proximal end and a distal end, whereby the distal end of the catheter is formed to include two inflatable balloons, wherein a multi-pole electrode is arranged on one side of each balloon so that each multi-pole electrode is aligned appropriately in the direction of the heart with the aid of each balloon, and wherein the distance between each of the balloons is adjustable.

2. Catheter device according to claim 1, whereby the balloon is filled with gas and/or a liquid.

3. Catheter device according to claim 2, whereby the liquid is a coolant.

4. Catheter device according to claim 1, whereby the shaft comprises a hollow channel through which another catheter can be introduced.

5. Catheter device according to claim 1 whereby the catheter comprises at least one temperature sensor which measures the temperature in the oesophagus and optionally comprises another temperature sensor.

6. Catheter device according to claim 1, whereby the catheter comprises at least one magnet on the side turned to the heart.

7. Catheter device according to claim 1, whereby the poles of the multi-pole electrode are arranged on two channels isolated from each other, whereby the channels are provided with small openings and whereby the channels can be moved against each other.

8. Catheter device according to claim 1, whereby the poles of the electrodes are formed as coils.

9. Catheter device according to claim 8, whereby the catheter further comprises shaft bearing the proximal pole of the electrode, while the distal pole inside the shaft is arranged so that it can be adjusted via a guide wire.

10. Catheter device according to claim 1, whereby at least one light diode is applied on the shaft running parallel in the same electrode plane.
