An interventional study of Modified Surgical Instruments/Devices (Sheaths and Irrigator) in Neural Tube Defects, sponsored by Michael A Belfort. Recruiting at 1 site in United States. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-12-15.
Sponsored by Michael A Belfort · Not applicable, Interventional, and Treatment
The purpose of the study is to evaluate the safety and efficacy of devices used in patients undergoing fetoscopic neural tube defect repair.
All patients who choose to undergo fetoscopic neural tube defect repair at Texas Children's Fetal Center will be offered participation in this research study by study investigators. Description of study rationale and design and a focused interview by the study coordinator to afford potential participants a formal opportunity to examine what they have learned about the research study in the course of their evaluation and discuss how they feel about enrolling in the research study. Once the patient is deemed eligible the informed consent process will be reviewed. If patients elect to participate in the study, informed consent will be obtained, and patients provided a copy of the signed consent.
Fetoscopic Procedure: The fetoscopic open neural tube defect repair procedure will be performed with the same technique in this protocol as the investigators did in the previous protocols under this IDE (NCT02230072 and NCT03794011) in terms of exteriorization of the uterus, preparation for the fetoscopic repair and repair of the open neural tube defect. This involves release of the placode, dissection of the surrounding skin, development of myofascial flaps on either side of the defect, placement of a patch to be laid on top of the placode prior to closure of the myofascial flaps, suture of the flaps over the freed placode and patch and attempted primary closure of the defect using available skin. If necessary, the surgeons will use relaxing incisions or a skin patch to provide additional mobility to the skin to be closed over the defect. If the surgeons are unable to close the skin primarily despite best fetoscopic efforts, the option of performing/completing the repair as an open procedure exists and will be offered to the subject.
Follow-Up: The investigators will follow patients for the immediate post-procedure period (until they leave the OR).
47 studies on the registry are indexed under Neural Tube Defects; 9 are open to participants now.
This study's planned enrollment of 100 is above the median of 47 across 26 interventional studies indexed under Neural Tube Defects.
