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.

Electrical lead for a catheter and method of manufacturing

An ablation catheter includes a control handle and a catheter sheath removably connectable to the control handle, the catheter sheath defining a fluid lumen and having a plurality of perforations proximal the distal end of the catheter sheath. The ablation catheter further includes a shape-imparting element inserted into the fluid lumen of the catheter sheath and removably connectable to the control handle. The shape-imparting element is connectable to an RF energy source so that, in use, the shape-imparting elements act as an electrode charging fluid into the fluid lumen to be expelled through the plurality of perforations on the catheter sheath.
