[A new needle for low risk amniocentesis in early pregnancy (author's transl)]

A new needle will be described, which has been especially useful for amniocentesis in early pregnancy. Construction is based on the principle of the Verres-needle. After passing through the abdominal wall and entering the amniotic sac, a blunt stylet prevents the needle from contacting the fetus. The depth of the puncture is controlled by a device attached to the side of the needle. The needle is easily observed using ultrasound because of good sound waves reflections of specially constructed surface.
