The need for OdonAssist™

Maternal and newborn health are primary areas of focus for governments and health agencies, and key areas of unmet need for innovation in medical technology.

Prolonged or complicated second stage of labour requiring an assisted vaginal birth or an emergency cesarean section occurs in approximately 10-15% of births12.

Assisted vaginal birth can be safer than an emergency cesarean section in the short and long term for mothers and babies, and should be recommended as the mode of delivery13.

In comparison with cesarean section, assisted vaginal birth is associated with a reduced risk of maternal haemorrhage14, intrapartum stillbirth16, admission to intensive care for newborns14, abnormally invasive placenta17 and stillbirth in subsequent pregnancies18.

How OdonAssist™

addresses the need:

1

In a clinical trial, women and midwives articulated views suggesting the common belief that forceps are more ‘traumatic’ either physically or emotionally2.

2

In a clinical trial, midwives perceived that the OdonAssist™ is kinder than other devices and described the births as ‘softer’, ‘nicer’, ‘beautiful’, ‘easy’, ‘smooth’ and ‘gentle’ 2.

3

In all clinical trials OdonAssist was demonstrated to be safe for the baby, with no typical pattern of the neonatal bruising or injury associated with use of forceps or vacuum extraction3-5.

4

The efficacy (successful assisted birth) rate with OdonAssist™ in clinical trials was up to 88.5%5.

5

If OdonAssist does not deliver the newborn it can be removed easily, allowing for other interventions.

6

Unlike forceps and vacuum extraction, with OdonAssist the insertion technique is the same for all fetal head positions in cephalic presentations3-5.
