1. A medical device comprising:
a sheath body comprising:
a first layer;
a second layer;
a third layer, wherein the second layer is disposed between the first layer and the third layer;
a braided wire assembly that is encased within the second layer;
a tracing support that is encased within the second layer, wherein the tracing support comprises a base layer, electrode tabs, and conductor traces, wherein each of the electrode tabs forms an electrode, wherein the conductor traces are disposed between the braided wire assembly and an outer surface of the second layer, wherein the electrode tabs and the conductor traces are formed by adding an electrically conductive material to the base layer via an electrical tracing process, a photo etching process, or an additive manufacturing process so that each of the conductor traces is connected to a respective one of the electrode tabs;
a central major lumen extending through the sheath body along a longitudinal axis, wherein the central major lumen is defined by the first layer;
at least one outer lumen extending through the sheath body, wherein the at least one outer lumen is disposed within the second layer; and
at least one deflection element extending through the sheath body; and
an actuator coupled to a proximal end of the sheath body, wherein the actuator is further coupled to the at least one deflection element and capable of deflecting a distal end of the sheath body.
