Patent ID: 7264613

Claim:
An IV catheter assembly comprising: a first hub comprising an exterior surface and an interior surface defining an interior cavity; a needle defining a needle shaft comprising a first dimension extending distally away from the first hub comprising a tip and a clip stopping section comprising a second different dimension positioned proximally of the tip; a second hub comprising an exterior surface and an interior surface defining an interior cavity; a catheter tube extending distally away from the second hub defining a lumen adopted to surround, at least in part, the needle shaft including the clip stopping section but not the tip; a tip protector comprising a proximal wall, which comprises a proximally facing wall surface, a distally facing wall surface, and a continuous perimeter defining an opening, and two resilient arms of different lengths extending distally of the proximal wall each comprising a radially extending member at an end thereof; the tip protector is moveable with the first hub and relative to the second hub in moving from a ready position to a protective position and the two resilient arms being biased radially when in the ready position; and wherein when the tip protector is in the protective position, by moving the first hub and the second hub relative to one another and causing the protective clip to move with the first hub relative to the second hub, the two resilient arms are no longer biased and move radially inwardly, the clip stopping section blocks the tip protector from further distal movement along the needle shaft, the two radially extending members block the tip, and the tip protector, including the proximal wall, remains with the needle.
