First probe monitors fetal health in utero during surgery
2 days ago
- Northwestern researchers developed the first device for continuous tracking of fetal vital signs inside the uterus.
- The soft, flexible robotic probe can be inserted through a narrow port already used in minimally invasive fetal surgeries.
- It tracks heart rate, heart rate variability, blood oxygen levels, and temperature simultaneously, providing real-time data.
- Studies on large animal models showed accurate, clinical-grade measurements even during surgical movements.
- The device enhances safety during fetal surgeries by enabling earlier detection of distress and faster interventions.
- Developed by bioelectronics pioneer John A. Rogers and fetal surgeon Dr. Aimen Shaaban, the probe builds on previous NICU monitoring technology.
- The probe uses soft robotic actuators and a tiny inflatable balloon cushion to maintain gentle, stable contact without additional incisions.
- Wireless transmission allows surgeons to monitor the fetus continuously, addressing a 40-year gap in monitoring capabilities.
