(A) The Franseen needle has a novel design of a crown tip with three-plane symmetric cutting edges. (B) The Reverse-bevel needle has a reversed-bevel system as a side-fenestrated opening on the needle shaft. (C) The Menghini-tip needle has a tapered bevel edge that facilitates the tissue being withdrawn into the lumen. Although it has a side port, it is classified as FNA needles because the side port of this needle system does not have any reinforcement geometries for cutting the tissue.
