A venous catheter having a catheter tip comprising recessed (248) diffusion holes (250,251) for increasing the snag-resistance of the venous catheter. Also disclosed are systems and methods for providing axial ridges (266) interposed between diffusion holes for increasing the rigidity of the vented catheter tip. By having the apertures within such portions recessed from the outer surface of the catheter tip snag-resistance is enhanced.
