Abstract
An electrode device for intracorporeal stimulation of body tissue, particularly for intracardial stimulation of the heart, has an electrode cable containing an elongated, flexible conductor having an exterior covered with a layer of insulation, and an interior forming a channel for the introduction of an elongated member for transmitting a pushing force to the distal (i.e., treatment site) end of the electrode for controlling the configuration of the electrode device as it is inserted in a patient. An electrode head is disposed at the distal end of the conductor. For making the electrode device pliant and elastic to facilitate implantation, even using an inserted stylet which need not be retracted, the elongated member in the interior of the conductor is made longitudinally stiff but has relatively large lateral flexibility.
