Abstract:
1. A neurostimulation catheter formed by a flexible tube of a non-electrically conducting material, a distal end of which is rounded, said neurostimulation catheter comprising an electric conductor which extends over a length of the flexible tube in order to conduct an electric stimulation current from one end of said flexible tube to the other end of said flexible tube, said electric conductor being formed by at least one layer of an electrically conducting material applied on an outer face of a sidewall of the flexible tube and a non-conducting cladding applied onto the electric conductor, said electric conductor forming at a distal end of the flexible tube a distal ring which fits a rounded shape of the distal end of the flexible tube and which is not covered by the non-conducting cladding so as to form a neurostimulation contact, and said electric conductor forming at a proximal end of the flexible tube a proximal ring which is not covered by the non-conducting cladding in order to achieve electric connection, and said non-conducting cladding extending along the whole length of the electric conductor between said distal ring and said proximal ring, said neurostimulation catheter further comprising a split conducting tube slipped onto the proximal end of the flexible tube in order to achieve electric connection with the proximal ring, wherein a wall of the split conducting tube is cut out longitudinally in order to form at least one elastic tab intended for providing electric contact between the proximal ring of the conducting layer and an electric wire maintained in contact with the tab.
