Design Specifications

The Odon Device is a vaginal delivery device that employs a circumferential air cuff over the fetal head to perform instrumental vaginal delivery. The product consists of a soft plastic cup that fits around the head of the baby, an inserter that grasps the head, and a polyethylene sleeve that is inflated with air that allows for the guidance of the baby out of the birth canal. A force of up to 19 kg can be applied to aid in the extraction process.
