The Study Device consists of two curved, rigid plastic-coated metal Arms with Handles which are used for control of the device outside the body, and an elastic Engagement Element which conforms to the maternal and neonatal anatomy, and which is used for direct contact with the entrapped neonate within the birth canal.

Первичные конечные точки

• Number of successful neonate deliveries with the Yaari Extractor device [Срок оценки: immediately after the intervention]
• Time interval (minutes) from the diagnosis of the shoulder dystocia until the neonate's delivery [Срок оценки: immediately after the intervention]
• Maternal and neonatal adverse events [Срок оценки: through study completion, an average of 5 days]

Вторичные конечные точки (1)

• Ease of Use 5 point Likert scale User Questionnaire [Срок оценки: immediately after the intervention]
