ABSTRACT:
A needle and a cover with a needle having an elongate shank and a tip with a sharpened point. The cover is coaxially associated with the elongate shank for movement therealong toward the tip and includes a part for extending beyond the sharpened point when the cover is positioned near the tip. A lock associated with the needle and cover cooperates and holds the cover to prevent axially movement relative to the needle tip after positioning the cover near the tip. The needle and cover may be a part of a catheter assembly having a catheter and an adapter connected to one another for fluid communication and carried coaxially about the needle and hub. The catheter has a bore therethrough sized to surround the elongate shank for movement therewith during insertion and therealong during placement. A retaining means on the adapter and on the cover releasably attach the cover to the adapter while on the elongate shank of the needle allowing the needle and cover to be disengaged from the catheter and adapter after placement.
