Brief summary

The EpiNo trial is trialing the use of a commercially available intravaginal balloon device in order to determine whether this device reduces the risk of major pelvic floor trauma at vaginal delivery.

Interventions

Use of intravaginal balloon device to distend pelvic floor muscle and reduce likelihood of traumas at childbirth, from 37 weeks' gestation to delivery. The patient inserts the device vaginally and inflates it intermittently, several times a day, to dilate the birth canal.
