1. A medical device, comprising:
an elongate shaft extending along a shaft longitudinal axis and comprising a shaft proximal portion and a shaft distal portion;
a navigational assembly connected to the shaft distal portion and extending along the shaft longitudinal axis, the navigational assembly defining an inner lumen passing therethrough along the shaft longitudinal axis, wherein the navigational assembly includes:
a central mounting bore that includes a bore proximal end and a bore distal end, the central mounting bore extending through the inner lumen defined by the navigational assembly;
a magnetic position sensor coil disposed about an exterior surface of the navigational assembly; and
a magnetic position sensor positioning feature defined in the exterior surface of the navigational assembly.
