Beschreibung
Zusammenfassung:	A catheter placement system including a catheter, a needle for creating an insertion site, and a skin nicking device for enlarging the insertion site. A catheter placement device includes the skin nicking device slidably coupled with the needle, where the skin nicking device has one or more blades attached to a frame thereof. Distally displacing the skin nicking device along the needle causes the blade to nick the skin to enlarge the insertion site. A shield of the skin nicking device transitions between a safe configuration encapsulating the blade and a use configuration exposing the blade and the shield may be biased toward the safe configuration. A latch secures the shield in the safe configuration and an actuator releases the latch. A sheath of the skin nicking device includes the needle slidably disposed within a lumen thereof and a sharp tip of the blade embedded within a wall thereof.
