Beschreibung
Zusammenfassung:	A medical insertion device includes an introducer assembly, a needle, and a housing. The introducer assembly includes a dilator coaxially disposed in a sheath, the dilator removably engaged to the sheath in an insertion configuration. The needle is coaxially disposed in the dilator, the needle having a distal tip and a proximal end coupled to a needle hub. The housing may be removably engaged to the dilator. The needle hub is movably disposed in the housing between a first locked position, in which the distal tip of the needle extends a first length from a distal end of the dilator, a second locked position, in which the distal tip of the needle extends a second length from the distal end of the dilator less than the first length, and a third locked position, in which the distal tip of the needle is within the dilator.
