Abstract:
1. A lead for an active implantable medical device, comprising: an elongated flexible sheath having a central lumen and at least one conductive connection housed in said central lumen of the sheath; and a rigid cylindrical supporting tube of an insulating material, having an outer surface, a central region, and a crossing central bore, the supporting tube being interposed in the sheath so that its central bore is coaxial with the lumen of the sheath; the supporting tube comprising: a cavity in its outer surface forming a chip receptacle, opening into the central region of the supporting tube, at least one electrode arranged on the supporting tube outer surface; and at least one chip comprising a substrate and at least two conductive contact pads comprising at least an outer conductive pad and an inner conductive pad, the outer conductive pad on a first side of the substrate and the inner conductive pad on a second side of the substrate, the at least one electrode being electrically connected to the outer conductive pad; and a feedthrough conductor having a central region connected to the inner conductive pad of the chip and two end regions, wherein: the substrate of the chip is a flexible substrate, disposed with a bent configuration in the receptacle of the supporting tube; the conductive connection housed by the sheath includes a disconnect at the supporting tube location; and the feedthrough conductor is a conductive strip formed on the outer surface of the supporting tube, and extending axially along the supporting tube and connected at each end region to the at least one conductive connection separated by the disconnect and located in the sheath.
