Abstract
Abstract A catheter needle assembly includes an injection-molded plastic body having a central hub portion through which a hollow core cannula extends, and from which a pair of wing-like tab portions extend in opposite directions to facilitate manipulating the assembly during use. Passageways extending through the roots of the tabs form crease lines to facilitate bending the tabs together for more convenient handling of the assembly.
