Defibrillation electrode

Abstract

A defibrillation electrode has a flexible electrode cable containing at least one elongated, electrically insulated conductors and having an electrode configuration attached at a distal end of the electrode cable. This electrode device configuration a number of elongated, flexible conductors, pre-shaped into an outward bulging configuration, having first ends anchored adjacent to each other at the distal end of the electrode cable, and second ends anchored adjacent to each other at a common connection point. To attain a defibrillation electrode which can be used for intracardial, epicardial and myocardial stimulation of the heart and which can be rapidly introduced into the patient, and applied to the myocardium or pericardium, with no need for major surgery, the conductors are spatially pre-shaped such that the anchored ends at the common connection point are twisted in relation to the anchored ends at the electrode cable's distal end. A device is provided for varying the relative distance between the conductors' anchored ends at the common connection point and the conductors' anchored ends at the distal end of the electrode cable.
