An acupuncture needle is an FDA approved Class II medical device in the same category as powered wheelchairs, infusion pumps, and surgical drapes. Class II devices are designed to perform as indicated without causing injury or harm to patient or user.
Acupuncture needles are typically made of stainless steel. They vary greatly in diameter and length. Some needles are finer than human hairs. Some needles are a few millimeters long while others can be over fifteen centimeters. In the USA, all needles used are disposable and for one-time use only.
