摘要
A lead for active implantable medical devices comprising a chip, notably for electrode multiplexing. The lead includes an insulating supporting tube interposed in a flexible elongated tube, with a central bore coaxial with the lumen of the lead. The supporting tube comprises on its surface at least one crossing conductive strip extending in the axial direction. A chip on a flexible substrate is disposed with a bent or curved conformation in a receptacle of the supporting tube isolated from the conductive strip. An electrode, e.g., for cardiac sensing/pacing, carried by the supporting tube is electrically connected to an outer conductive pad of the chip. The conductive strip is connected (i) at each end, face to face to a conductive connection, housed in the sheath, and (ii) in a central region, to an inner conductive pad of the chip.
