An Extractor for the Management of Shoulder Dystocia.

Abstract

The Yaari Extractor is intended to wrap around and guide the fetal shoulder to facilitate vaginal delivery in cases of shoulder dystocia. The Yaari Extractor is a single-use device for fetal shoulder extraction. The device consists of two curved, rigid plastic-coated metal arms with handles and an elastic engagement element that includes two hollow sleeves that cover the portion of the device that enters the vagina and contacts the fetus. The device has been used in three cases of shoulder dystocia. In all three cases, the shoulder dystocia was resolved without the need for ancillary obstetric maneuvers, and there was no reported maternal or fetal injury. The Yaari Extractor is a novel technology that can be used to successfully resolve shoulder dystocia.
