Huber point or non-corning needles are designed with a deflected or offset ‘B’ bevel point. This tip has the advantage of parting rather than cutting a plug from or coring the silicone septum of a vascular access port or injection site. This preserves the integrity of the septum and prevents a silicone plug being cut and passed into the vasculature.

Notice that the bevel of the Huber point needle, i.e. the ground surface or cutting edge, is almost perpendicular to the needle shaft. This deflects the pressure from the heel, allowing the needle to part rather than core the septum as it is inserted and withdrawn.
