A therapy delivery element including a plurality of fibers braided to form an elongated braided structure with a lumen. At least one reinforcing structure is woven into the fibers of the braided structure. A portion of at least one reinforcing structure extends from the braided structure to form a fixation structure. A conductor assembly including a plurality of conductors is located in the lumen. An electrode assembly is located at a distal end of the conductor assembly. The electrode assembly includes a plurality of electrodes that are electrically coupled to the conductors. A connector assembly is located at a proximal end of the conductor assembly. The connector assembly includes a plurality of electrical contacts that are electrically coupled to the conductors. At least one of the braided structure or the reinforcing structure is attached to at least one of the electrode assembly or the connector assembly.
