Brief 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 3 months from the time of the use of the device during delivery. Subjects who elect to continue participation in the long term follow up portion of the study will extend their time in the study to 10 years.

Condition or disease Intervention/treatment Phase
Childbirth Device: Materna Prep Device Other: Standard of Care (SOC) Not Applicable

Detailed Description:

Primary effectiveness endpoint: Reduction in the rate of pelvic muscle injury defined as complete or partial detachment of the levator ani muscle diagnosed via ultrasound imaging at 3-month follow-up.

Primary safety endpoint: Data on maternal and neonatal adverse events will be gathered and evaluated. Adverse events will be further summarized by relatedness to the device and/or procedure, seriousness, and level of severity.

Secondary endpoints

  • Reduction in the length of second stage of labor, defined as the time from when the cervix is dilated to 10cm to the complete delivery of the baby.
  • Reduction in Levator Hiatus Area (measurement between pelvic muscle and pelvic bone) determined at 3-month ultrasound follow-up.
  • Reduction in the rate of perineal lacerations determined by visual inspection post-delivery.
  • Reduction in the rate of instrument use in vaginal deliveries.
  • Reduction in the rate of OASI
  • Rate of C-Sections due to cephalopelvic disproportion.
  • Infant APGAR scores.
  • Qualitative pain and pelvic health feedback.
  • User satisfaction

  3. Reduce Perineal Lacerations [ Time Frame: Intra-Procedure ]
    Reduce the rate of perineal lacerations between device and control groups

  4. Reduction in the rate of instrument use in vaginal deliveries [ Time Frame: Intra-Procedure ]
    Reduce use of instrument during deliveries

  5. Reduction in the rate of OASI [ Time Frame: Intra-Procedure ]
    Reduce the tearing of the muscles of the anal sphincter

  6. Reduction of C-Sections due to cephalopevic disproportion [ Time Frame: Intra-Procedure ]
    Reduce the rate of C-Sections

  7. Infant APGAR scores [ Time Frame: Intra-Procedure ]
    Increase APGAR scores

  8. Qualitative pain and pelvic health feedback [ Time Frame: 3-Month Follow-up ]
    Reduce pain and pelvic injury

  9. User Satifaction [ Time Frame: 3-Month Follow-up ]
