Myelomeningocele Clinical Trial
— HUC-FICSOfficial title:
Cryopreserved Human Umbilical Cord as a Meningeal Patch in Fetoscopic Spina Bifida Repair: Single Arm Phase III Trial.
The objective is to test the efficacy of a laparotomy-assisted fetoscopic surgical approach to cover spina bifida spinal cord developmental defects using cryopreserved human umbilical cords (NEOX Cord 1K®) as a meningeal and skin patch.
