Abstract
An obstetrical vacuum extractor having a vacuum cup molded of a first, relatively rigid material, with a lip of a second, relatively soft material secured along the basal opening. An elongated hollow stem which may be coupled to a vacuum source communicates with the interior and, accordingly, the basal opening of the vacuum cup. The first, relatively rigid material of the cup is preferably substantially transparent so that the physician may readily monitor the condition of the fetal scalp throughout delivery.
