Abstract
A catheter and introducer needle assembly with a compact needle shield is provided wherein the needle includes a discontinuity thereon, which may take the form of an enlarged diameter portion. The needle shield includes a spring clip that engages the enlarged diameter portion to prevent unwanted proximal and distal movement of the needle once the needle has been withdrawn into the needle shield.
