Description

Summary

This study is designed to evaluate the safety and effectiveness of the Materna Prep Device in reducing pelvic muscle injuries during vaginal delivery.

Subjects are randomized to Materna Prep Device or Standard of Care without use of the Materna Prep Device

Intervention with the Materna Prep Device is expected to be a one-time use of approximately 30-90 minutes during the 1st stage of labor.

Subject participation in the study is targeted to be 12 months from the time of the use of the device during delivery.

Official Title

A Randomized, Controlled Study to Evaluate the Safety and Effectiveness of the Materna Prep Device to Pre-stretch the Vaginal Canal and Pelvic Floor Tissues in Preparation for Vaginal Delivery

Details

Vaginal delivery is a major risk factor for pelvic floor dysfunction. Clinical aspects of pelvic floor dysfunction include pelvic organ prolapse, sexual dysfunction, and fecal and urinary incontinence. Trauma to the pelvic structures occurs as the fetal head passes through the vaginal canal, especially with acute distension at the time of crowning - the exiting of the fetal head.

The Materna Prep Device is a single-use, semi-automated dilator used during the first phase of labor in order to prepare the vaginal canal for vaginal delivery. By slowly pre-stretching the vagina and surrounding pelvic tissues during labor, the device is essentially dictating the strain rate of the tissue during labor. In previous feasibility studies, the elastic recovery of the tissue has been shown to be on the order of several hours, allowing the benefits of pre-stretching the vagina and surrounding pelvic tissues to last throughout labor. The device is intended to be removed prior to the initiation of the second stage of labor, for delivery to occur unobstructed.

The target patient population for this study is nulliparous women entering the first phase of labor and scheduled for vaginal delivery with an epidural.

Criteria for exclusion

  1. Subject has high likelihood of less than 1 hour of potential device dilation time after she arrives at the hospital.
  2. Subject is planning or requires a Caesarean-section prior to randomization.
  3. Subject begins labor with less than 36 weeks gestation.

  5. Subject has a collagen-associated disorder that affects tissue elasticity, such as scleroderma or Ehlers-Danlos syndrome.
  6. Subject has a localized (genital tract) or systemic infection.
  7. Subject has a medical history which could lead to pelvic floor dysfunction, such as prior pelvic fractures, pelvic soft tissue injuries, or vaginal surgery.
  8. Subject has any general health condition or systemic disease that may represent, in the opinion of the Investigator, a potential increased risk associated with device use or pregnancy.
  9. Subject has placenta previa or vasa previa.
  10. Subject has known significant chromosomal or structural fetal anomalies.
  11. Subject has a category 2 and/or 3 fetal tracing that is unresolved.
