an elongate body including:
an inner member having a proximal portion and a distal portion with a first passage defined between the proximal and distal portions; and
an outer member extending distally past the inner member and defining a second passage, the inner member disposed within the second passage; and
a plug having a proximal section and a distal section, the proximal section positioned within the first passage in the distal portion of the inner member to partially occlude the first passage, the plug being substantially cylindrical and having a flat parallel to and offset from a longitudinal axis of the plug, the flat defining a gap with the elongate body, the distal section of the plug extending distally from the proximal section and positioned outside of the first passage and within the second passage.
