1. An apparatus, comprising:
an elongated dilator assembly defining a lumen; and
an elongated needle assembly configured to be receivable and movable within the lumen; and
a stop-movement device having a generally cylindrical body defining a longitudinal interior passage including,
a first inner wall surface having a first interior dimension and configured to engage a portion of the elongated dilator assembly,
a second inner wall surface adjacent the first inner wall surface, the second inner wall surface having a second interior dimension and configured to engage a portion of the elongated needle assembly, the first interior dimension being greater than the second interior dimension, and
a step disposed in the interior passage at an intersection of the first and second inner wall surfaces and configured to be mounted to the elongated needle assembly and the elongated dilator assembly after the elongated needle assembly, in use, is received, at least in part, inside the lumen of the elongated dilator assembly; and

wherein the step of the stop-movement device is configured to contact a proximal end of the elongated dilator assembly so as to inhibit relative movement between the elongated needle assembly and the elongated dilator assembly in a distal direction.
