a needle having a sharp needle tip, a needle stop, and defining a longitudinal axis connected to a needle hub and disposed
in the catheter tube; the needle hub comprising a shroud attached thereto and not separable during use, said shroud comprising
a slit and an outer radial dimension relative to the longitudinal axis; and
a needle guard disposed about the needle; the needle guard comprising a proximal wall, which has an opening, an arm, which
has a distal portion, extending from the proximal wall, and second arm; and wherein the arm and the second arm are removably
