ABSTRACT:
An implantable improved three-pole electrocatheter for permanent cardiac stimulation. The electrocatheter is of the type which comprises a flexible body which extends predominantly axially, is made of biocompatible material and can be surgically inserted through a vein until it reaches the cardiac muscle with a terminal portion. The terminal portion is equipped with a ventricular electrode at its end and has, on its outer surface, a pair of atrial electrodes which are appropriately spaced from one another and with respect to the ventricular electrode. On the side opposite to the terminal portion, the flexible body is provided with connections which are electrically connected to the atrial and ventricular electrodes. The electrocatheter is characterized in that the electric connections comprise a three-pole connector to which the electrodes are connected by means of coiled insulated conductors. The coils defined by the conductors are coaxial.
