The invention relates to a method and a device for detecting the contact and/or interaction of a catheter with the tissue of a patient, said catheter being positioned in a vessel of the patient, especially in the bloodstream of the patient. The aim of the invention is to help provide better detection of such contact or to make it possible to provide certain information during an ablation procedure as to the depth of ablation or interaction with the tissue. To this end, a device for detecting a voltage at at least one catheter electrode is provided. According to the invention, the voltage between the catheter electrode and the additional electrode is measured, said additional electrode being an indifferent electrode which is in contact with the body of the patient being treated or another electrode attached to the catheter.
