ABSTRACT:
A device to assist in removing a fetus from a woman's birth canal during childbirth is provided. The device includes a pliable, elongated member open at at least one end to fit over the head of the fetus, insertion means for positioning the elongated member over the head of the fetus, and restricting means attached at that one end of the elongated member to decrease the size of the opening at the one end. The elongated member is constructed so that as the elongated member is pulled from the other end, the elongated member will axially grip the head of the fetus.
