Abstract
A medical device may include a sheath extending from a proximal end to a distal end. The medical device may further include a light source coupled to the sheath. The light source may have a first state in which light is not emitted distally of sheath and a second state where the light source emits a visual pattern distally of the distal end of the sheath. The visual pattern may represent a cross-sectional dimension of a structural feature of the sheath.
