Abstract: A device for storing a stylet comprises a stylet sized and shaped for insertion into a lumen of a needle and an end cap selectively coupleable to a proximal end of a needle, the end cap being coupled to a proximal end of the stylet so that, when the end cap is coupled to the needle, the stylet extends from the end cap through the lumen of the needle, the end cap including a clip mechanism for gripping a distal end of the stylet when the end cap is decoupled from the needle, the clip mechanism including a space through which the distal end of the stylet may pass substantially parallel to the proximal end thereof.
