1. A mapping overlay of a mapping catheter, the mapping overlay comprising:
an elongate, flexible tubular body;
a mesh of wires forming a tubular sidewall of a cavity configured to receive a treatment device therein, the mesh of wires comprising:
a plurality of conductor wires, and
a plurality of structural wires formed of a different material than the plurality of conductor wires, wherein the plurality of conductor wires and the plurality of structural wires are braided to form the mesh of wires;
a plurality of sensors on the plurality of conductor wires;
a cap coupled to a distal end of the mesh of wires, the cap comprising a lumen extending through the cap to permit a wire to extend past a distal end of the cap; and
a catheter body coupled to the mesh of wires, the catheter body comprising:
one or more inner layers,
one or more outer layers being coupled to the one or more inner layers such that the one or more outer layers are axially fixed relative to the one or more inner layers, and
a treatment device lumen extending through the catheter body and opening into the cavity to permit a separate treatment device to be expanded within the cavity;
wherein at least a portion of the mesh of wires is located between the one or more inner layers and the one or more outer layers, and the mesh of wires extends past a distal end of the catheter body.
