An intracardial electrode lead comprises a distal end, a proximal end and an elongate electrode lead body which includes a helical coil having a lumen and a sheath enclosing the helical coil. The distal end of the electrode lead carries a an electrode. The electrode is electrically connected to a connection at the proximal end of the electrode lead for communication with a medical device. The distal end has a sleeve with a proximal end and a distal end, which is enclosed by the distal end of the helical coil at the sleeve proximal end and contacts a lip seal at its distal end. The lip seal elastically closes a distal opening of the lumen. The sleeve is also electrically connected to the electrode, which has an external surface and projects distally beyond the lip seal.
