An amniotic perforator is a highly specialized medical instrument that doctors and midwives use to safely tear the amniotic sac. This procedure is commonly called amniotomy (where a doctor and midwife intentionally rupture the amniotic sac during labor). It essentially acts as a controlled way of breaking the water. Amniotic Perforator is used by qualified doctors and midwives experienced in performing amniotomy procedures. The decision to perform an amniotomy is based on individual patient factors and the stage of labor.
