Brief Summary:

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

Intervention with the Materna Prep Device is expected to be a one-time use of 30-90 minutes. Total subject participation in the study is expected to be up to 4 months from the time of initial enrollment. All evaluations prior to and after delivery can be performed on an outpatient basis. The Materna Prep Device is a vaginal dilator used to pre-stretch the vaginal canal to shorten the length of second stage of labor in preparation for vaginal delivery.

This is randomized, controlled study designed to evaluate safety and effectiveness of the Materna Prep Device in pre-stretching the vaginal canal in preparation for vaginal delivery. The primary effectiveness endpoint is the length of the second stage of labor, defined as the time from the cervix being dilated to 10cm to the complete delivery of the baby. 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.

There are three secondary endpoints:

Rate of pelvic muscle injury defined as either complete separation of the puborectalis muscle, partial separation of the puborectalis muscle, or anal sphincter disruption diagnosed via ultrasound imaging at 3-month follow-up.

Length of Pushing Time, defined as the time from when the mother begins pushing to the complete delivery of the baby.

Levator Hiatus Area (measurement between pelvic muscle and pelvic bone) determined at 3-month ultrasound follow-up.

Criteria

Inclusion Criteria Subject scheduled for vaginal birth. Subject gestating a single fetus. Subject primiparas, or had a previous pregnancy terminated within 24 weeks gestation.

Subject able and willing to comply with the protocol required follow-up visits. Subjects able and willing to provide written informed consent prior to enrollment.

Subject has sufficient mental capacity to: understand the informed consent form (ICF), comply with the protocol requirements, and provide clinically relevant and reliable feedback regarding their experience with the device.

Subjects agrees that anonymized personal data will be made available to study Sponsor and requisite regional and international regulatory bodies.

Exclusion Criteria Subject has high likelihood of less than 1 hour of potential device dilation time after she arrives at the hospital Subject has need for or is planning a Caesarean-section Subject begins labor with less than 36 weeks gestation Subject had previous delivery or previous pregnancy progressing beyond 24 weeks gestation Subject has neurological diseases, e.g. Multiple Sclerosis, that may result in unrelated pelvic disorders Subject has muscular or skin disorder that affects elasticity of tissue, such as scleroderma or lupus.

Subject has local or systemic infection e.g. HIV, or active herpes infection Subject has any prior surgical procedures to the vaginal anatomy which could lead to pelvic dysfunction, pelvic fractures, or pelvic soft tissue injuries 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.
