NOW ENROLLING - Materna Prep Clinical Trial

A study investigating the influence of the Materna Prep device in first-time moms on pelvic muscle injuries with delivery and the length of the labor.

Goals of Study

To understand if using the Materna Prep device may help:

  • Prevent pelvic muscle injuries
  • Minimize tearing
  • Impact time spent in labor

Learning About Vagina and Pelvic Muscles

Just like stretching before a run, we want to see if using Materna Prep a few hours before delivery will help vagina and pelvic muscles in similar ways.

Funded by The National Institutes of Health (NIH)

CAUTION:  Investigationl medical device. Limited by United States law to investigational use.

Study Visits

Day of Delivery

A dedicated research coordinator will work with you during Materna Prep's study. Your OB/GYN or midwife will continue with your clinical care.

Materna Prep is inserted a few hours before giving birth and gradually expands over an hour. Before the baby is delivered, Materna Prep is removed.

Three months after delivery

A follow-up exam and ultrasound will occur, which can coincide with your normal OB/GYN or midwife appointments.


You may qualify if you are a first-time mother who is at least 18-years old, you and your doctor or midwife expect you will deliver at full term, will have a vaginal delivery, and if you plan to use an epidural.

Ask your doctor or midwife if the Materna Prep Clinical Trial is right for you.
