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.

The needles are generally made of stainless steel. They vary greatly in diameter and length. Some needles are finer than human hairs while others are as thick as fine hypodermic needles. Some needles are a few millimeters long while others can be over fifteen centimeters.

An acupuncture needle is a stainless steel needle that is slightly thicker than a human hair. Acupuncture needles are inserted through the skin at specific points on the body to control pain and other symptoms.
