AN ELECTRICAL LEAD FOR A CATHETER AND METHOD OF MANUFACTURING

摘要

An electrical lead for a catheter includes an elongate member of non-conductive material having a proximal end and a distal end and defining a lumen extending from the proximal end to the distal end. The elongate member further includes a tubular member of non-conductive material, a braid of conductive material applied over the tubular member, an intermediate layer of non-conductive material applied over the braid, a plurality of electrical conductors extending from the proximal end to the distal end laid on the intermediate layer, and an outer layer of non-conductive material applied over the electrical conductors to cover the conductors. At least one electrode is arranged on the outer surface of the elongate member in electrical communication with at least one of the plurality of electrical conductors through the outer layer. The braid underlies the at least one electrode but is insulated from the at least one electrode by the intermediate non-conductive layer.
