Abstract
A head for an obstetric vacuum extractor has a convex distal part reconfigurable into a concave suction cup. For example, the head may comprise single-walled distal and proximal parts, wherein the distal part can be deformed to create a double-walled suction cup in cooperation with the proximal part. Thus the head may be inserted into the mother's vagina, the head having a convex distal part upon insertion, whereupon the convex distal part is reconfigured into a concave suction cup for engagement with the baby's head, suction is applied to the cup to attach the cup to the baby's head, and force is applied to the baby's head via the cup to aid delivery.
