Controllable intracardial electrode device

Abstract

A controllable electrode device for intracardial stimulation of the heart with an electrode cable includes an elongate, flexible conductor having an exterior covered with a layer of insulation and an interior forming a lumen for the introduction of an element for assisting in guiding the electrode device through a vein, and having an electrode head fitted at the conductor's distal end for stimulation of cardiac tissue. In order to achieve an electrode device with an electrode cable which is pliant and flexible, at least in its anterior section, to promote being guided through a vein, and which can be guided and shaped in the heart in a desired manner, a guide arrangement is provided which includes an elongate element having at least one groove running roughly perpendicularly to the longitudinal direction of the element and having a shape and depth enabling the element, and therefore the electrode cable, to bend at the groove when the element is subjected to pressure in its longitudinal direction.
