Patent ID: 7963943

Claim:
An I.V. catheter assembly and needle safety device comprising: a catheter assembly including a catheter and a catheter hub; a lock assembly including a housing, a locking member and a resilient locking clip, the housing defining a throughbore and having a distal end configured to engage a proximal end of the catheter hub, the locking member defining a throughbore and being rotatably supported within the housing throughbore, the housing throughbore defining a longitudinal channel, which is sized to accommodate the resilient locking clip, wherein the resilient locking clip is supported on the locking member, the resilient locking clip being rotatable with the locking member from a first position misaligned with the longitudinal channel to a second position aligned with the longitudinal channel to substantially prevent rotation of the locking member with respect to the housing; and a needle having a distal tip, the needle being positioned through the housing throughbore, the locking member throughbore and the catheter in an advanced position such that the distal tip of the needle projects from a distal end of the catheter, the needle being movable from the advanced position to a retracted position, wherein the distal tip of the needle is positioned within the housing, the needle having a first portion movable through the locking member throughbore, the first portion being configured to effect rotation of the locking member with respect to the housing as the needle is moved linearly through the locking member throughbore.
