ABSTRACT:
A multipolar cardiac pacemaker lead wherein the distal end carries a first electrode and at least one sleeve-like additional electrode is provided between the first electrode and the proximal end. Each additional electrode is positively connected with a corresponding helically wound wire-like conductor of the lead by a tubular conductor within an insulating sheath of the lead and by one or more flexible metallic bands each of which has a distal portion soldered or welded to the internal surface of the respective additional electrode, a second portion soldered or welded to the respective tubular conductor, and an S-shaped or Z-shaped intermediate portion extending between and contacting the adjacent convolutions of the respective wire-like conductor. Each tubular conductor is welded or soldered to at least one adjacent convolution of the corresponding wire-like conductor. The wire-like conductors are electrically insulated from each other.
