Brief Summary
The purpose of this study is to demonstrate the ability to prenatally deflate and to evaluate the safety of the Smart-TO device for fetoscopic endoluminal tracheal occlusion (FETO) in fetuses with congenital diaphragmatic hernia and moderate to severe pulmonary hypoplasia.

Outcome Measures
Primary Outcomes (1)
To demonstrate the ability to prenatally deflate the Smart-TO balloon by the magnetic fringe field generated by an MRI scanner
• Deflation rate after MRI exposure, assessed through ultrasound (US) immediately after MRI exposure
Up to 34+6 weeks of pregnancy
Secondary Outcomes (5)
Balloon expulsion from the fetal airways after deflation.
Immediately after MRI exposure
Rate of spontaneous deflation of the balloon.
Up to 34+6 weeks of pregnancy
Percentage of lung growth
Two weeks after FETO
Number of adverse events related to the balloon.
From date of inclusion until date of discharge from the hospital
Balloon localisation at birth
At birth
Study Arms (1)
Procedure FETO with the Smart-TO balloon
EXPERIMENTALFetal endoscopic tracheal occlusion using the Smart-TO balloon. Balloon removal procedure by peripheral course around the MR scanner
Interventions
Fetal Endoscopic Tracheal Occlusion using the Smart-TO balloon and non-invasive balloon removal by the peripheral magnetic field of an magnetic resonance scanner.
Eligibility Criteria
You may qualify if:
- Women carrying a fetus with isolated CDH eligible for FETO, i.e. with severe or moderate hypoplasia:
- Left sided CDH with severe (i.e. quotient of observed-to-expected- lung-to-head ratio under 25%) or moderate pulmonary hypoplasia (observed-to-expected- lung-to-head ratios of 25 to 34.9% (any liver position), or 35 to 44.9% with intrathoracic liver herniation)
- Right sided CDH with severe pulmonary hypoplasia (quotient of observed-to-expected- lung-to-head ratio under 50%)
- Voluntary written informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures
- Maternal age of 18 years or older
- Single pregnancy
- Signed informed consent
- Consent to have an ultrasound of the uterus after delivery when indicated
- Postnatal management center agrees to participate
You may not qualify if:
- Participants eligible for this Trial must not meet any of the following criteria:
- History of allergy to latex
- Contraindication to fetoscopy and FETO (maternal diseases or technical limitations making prenatal surgery hazardous or impossible)
- Premature Membrane Rupture (PROM)
- Multiple pregnancy
- Maternal age less than 18 years
- Refusal to stay close to the UZ Leuven until balloon removal
- Any disorder, which in the Investigator's opinion might jeopardise the participant's safety or compliance with the protocol
- Any prior or concomitant treatment(s) that might jeopardise the participant's safety or that would compromise the integrity of the Trial
- Participation in another interventional trial with an investigational medicinal product (IMP) or device
