Declarations under Rule 4.17: as to the applicant's entitlement to claim the priority of the earlier application (Rule 4 . 1 7 (iii)) Published: — with international search report (Art. 21(3)) (54) Title: INTRAVENOUS CATHETER ASSEMBLY WITH SAFETY CLIP (57) : A catheter assembly (20) includes a catheter (24), a catheter adapter (26), a needle (22), a needle guard (33) and a housing (50). The housing (50) is coupled to the needle guard (33) and disposed within a lumen (30) of the catheter adapter (26). The needle guard (33) may include first and second resilient arms (40a,b), which may include first and second curved portions (42), respectively. When the needle (22) is in a ready position, the first and second curved portions (42) are urged by a shaft (34) of the needle (22) into retaining contact with an inner wall (28) of the catheter adapter (26). When the needle (22) is in the retracted position, the shaft (34) may no longer bias the first and second resilient arms (40a,b) outwardly such that the retaining contact between the first and second curved portions (42) and the catheter adapter (26) is released, and the housing (50) and the needle guard (33) enclose a distal tip (36) of the needle (22).
