ABSTRACT:
The catheter assembly of the present invention comprises (i) a needle component, (ii) a catheter component mounted on the needle component in a manner that permits relative axial movement between the needle component and the catheter component, and (iii) a rotatable screw means for controlling the relative axial movement between the needle component and the catheter component and for inducing rotational movement to the catheter component. The improved catheter assembly of the invention facilitates the insertion of the catheter component into a vessel of a patient and permits precise control of the relative positions of the components of the assembly to one another. In one application, the invention provides an improved intravenous catheter (I.V. catheter).
