1. A location detection system, comprising:
an elongate body defining a lumen at least partially along a length of the elongate body;
one or more sensors positioned near or at a distal tip of the elongate body;
one or more openings defined along the elongate body in proximity to the one or more sensors;
a fluid with a parameter of a known initial value when emitted from the one or more openings; and
a controller in communication with the one or more sensors, wherein the controller is configured to track a change in the parameter relating to concentration of the fluid after being emitted from the one or more openings and passing over the one or more sensors and wherein the controller is further configured to determine a position of the one or more sensors within a body of a subject based upon the dilution of the fluid after being emitted.
