<unk>  (VE), also known as ventouse, is a method to assist delivery of a baby using a<unk>  device. It is used in the second stage of labor if it has not progressed adequately. It may be an alternative to a forceps delivery and caesarean section. It cannot be used when the baby is in the breech position or for premature births. The use of VE is generally safe, but it can occasionally have negative effects on either the mother or the child. The term comes from the French word for "suction cup".
