简要总结

The goal of this clinical trial is to learn about the safety and performance of the INGA Sensor System when used with the INGA balloon catheter during cervical ripening for labor induction in pregnant individuals at term. Cervical ripening is a process used to prepare the cervix for labor.

The main questions it aims to answer are:

  • Is the INGA Sensor System safe to use during cervical ripening with the INGA balloon catheter?
  • How well does the sensor system measure uterine contractions and fetal heart rate during cervical ripening?
  • How does the use of the INGA balloon catheter affect cervical ripening and the time from induction to delivery?
  • How do participants and healthcare professionals evaluate the usability of the catheter and sensor system?

All participants in this study will receive the INGA balloon catheter with the attached sensor system. There is no comparison group.

Participants will:

  • Undergo routine assessments before labor induction, including medical history review, cervical examination, blood pressure and heart rate measurement, and fetal heart rate monitoring
  • Have the INGA balloon catheter placed in the cervix by a trained physician
  • Have a small sensor device attached to the external end of the catheter
  • Undergo standard fetal heart rate monitoring after placement
  • Keep the catheter and sensor in place until the catheter is expelled naturally or for up to 24 hours
  • Continue labor induction and delivery according to standard hospital practice
  • Complete a questionnaire about comfort and usability
  • Allow collection of information about labor, delivery, and newborn outcomes from medical records

Participation lasts from signing informed consent until hospital discharge.

详细描述

This is a prospective, single-arm, early feasibility clinical trial designed to evaluate the safety, performance, and usability of the INGA Sensor System when used together with the INGA cervical ripening catheter during induction of labor in pregnant individuals at term. Approximately 120 participants are planned to be enrolled.

The primary objective of the study is to evaluate the performance of the INGA Sensor System in providing clinically interpretable data on fetal wellbeing and induction progress during cervical ripening. A successful measurement is defined as the sensor providing interpretable signal data for at least 10 consecutive minutes.

Secondary objectives include evaluation of device usability, technical performance, maternal and neonatal safety, and obstetric outcomes such as change in Bishop score, induction-to-delivery interval, and mode of delivery.

Participation lasts from signing informed consent until hospital discharge following delivery.

研究组 & 干预措施

INGA Sensor

Experimental

Participants in this single study arm will undergo cervical ripening using the INGA balloon catheter with the attached INGA sensor during labor induction. The catheter is inserted vaginally through the cervical canal so that the balloon tip is positioned between the amniotic membranes and the internal cervical os. The balloon is inflated with 50-75 mL of sterile saline and the external end is secured to the inner thigh. The INGA sensor is attached to the external portion of the catheter and records maternal and fetal data, such as heart rate and uterine contractions. Clinical monitoring is performed according to hospital guidelines. CTG monitoring is conducted for at least 60 minutes after placement. The sensor remains in place until catheter detachment or up to 24 hours.

干预措施: Cervical ripening, labor Induction, uterus and fetal monitoring (Device)

结局指标

主要结局
