Abstract
Abstract A vacuum extractor for extracting a fetus from a birth canal during childbirth is provided. The vacuum extractor includes a cup, a stem, and a handle. The handle has a first end, a second end, and a passageway extending therethrough from the first end to the second end. The handle is connected to the stem such that the first and second ends of the handle extend substantially laterally from the stem and the passageway of the handle in fluid communication with the vacuum cup. The first end of the handle is adapted to be connected to a vacuum source, and the second end is adapted to receive a vacuum release valve.
