A Tuohy needle is a hollow hypodermic needle, very slightly curved at the end, suitable for inserting epidural catheters.
The needle features an anti-coring curve at its tip (as shown in the picture above left) designed to cause a catheter passing through the needle's lumen to exit laterally at a 45 degree angle.
