Abstract
An electrode apparatus, such as an intravascular or intracardiac pacemaker or defibrillation electrode with an electrode cable has a jacket of insulation enclosing a first elongated, flexible conductor, connected to a first electrode arranged on the electrode cable, and also enclosing at least a second conductor, connected to a conductive surface forming a second electrode arranged on the electrode cable at a distance from the first electrode. In order to achieve an electrode apparatus with which the distance between the electrode on the electrode cable cart be changed in a very simple manner and in which the surface area exposed to tissue of at least one electrode can be enlarged, reduced and even rotated around the electrode cable in certain instances, the electrode apparatus is equipped with at least one sleeve-like body, insulated against the surroundings and slidable on the electrode cable, which at least partially covers the conductive surface and with which the second electrode can be formed whose position in relation to the first electrode and/or whose size can be varied.
