<p>The lead (24) has a telescopic microcable made of conductive material and possessing diameter ranging between 0.5 and 2 French unit. The microcable has a multi-wire structure and a set of strands twisted together, where some of the strands incorporate a core that is made of radiopaque material and is wrapped by a sheath made of mechanically durable material, or vice versa. The microcable has a proximal end and a distal end whose active free part (34) comprises a set of distinct bare helical regions that forms a network of stimulation electrodes electrically connected together. The multi-wire structure is coated with insulating material i.e. Parylene(RTM: conformal protective polymer coating material). The bare helical regions are isolated from each other by helical coatings made of electrically non-conductive material.</p> |
