A medical, implantable electrode device, in particular a cardiological electrode device, comprises an elongate electrode body (2) having a proximal and a distal end (1) for insertion into the body of the patient and multiple strut-like anchoring elements (4), which are attached laterally to the electrode body (2) before the distal end (1) for fixing the electrode device in the patient and are distributed around the circumference, which each project having their longitudinal axis (SL) at an acute angle (W1) opening in the direction of the proximal end in relation to the electrode body axis (KL). The anchoring elements have a preferred direction around the circumference in such a way that upon engagement of the anchoring elements (4) in a body part of the patient, a rotation of the electrode body (2) is opposed by a greater resistance in one rotational direction than in the opposite direction.
