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.
