Oesophageal electrode probe and device for cardiological treatment and/or diagnosis

Abstract

The invention relates to an oesophageal electrode probe (10) for bioimpedance measurement and/or for neurostimulation; a device (100) for transoesophageal cardiological treatment and/or cardiologicaldiagnosis; and a method for the open-loop or closed-loop control of a cardiac catheter ablation device and/or a cardiac, circulatory and/or respiratory support device. The oesophageal electrode probecomprises a bioimpedance measuring device for measuring the bioimpedance of at least one part of the tissue surrounding the oesophageal electrode probe. The bioimpedance device comprises at least onefirst and one second electrode, wherein the at least one first electrode (12A) is arranged on a side (14) of the oesophageal electrode probe facing towards the heart and the at least one second electrode (12B) is arranged on a side (16) of the oesophageal electrode probe facing away from the heart. The device (100) comprises the oesophageal electrode probe (10) and a control and/or evaluation device (30), which is configured for receiving a first bioimpedance measurement signal from the at least one first electrode (12A) and a second bioimpedance measurement signal from the at least one secondelectrode (12B), and comparing same, and generating a control signal on the basis of the comparison. The control signal can be a signal for the open-loop or closed-loop control of a cardiac catheterablation device and/or a cardiac, circulatory and/or respiratory support device.

Problems solved by technology

However, continuous temperature monitoring is usually not sufficient to ensure a high degree of safety in ablation or catheter ablation because tissue damage is already present when a significant increase in temperature is detected
