New device permitting non‐invasive reversal of fetal endoscopic tracheal occlusion: ex‐vivo and in‐vivo study

One of the drawbacks of fetal endoscopic tracheal occlusion (FETO) for congenital diaphragmatic hernia is the need for a second invasive intervention to re‐establish airway patency. The ‘Smart‐TO’ device is a new balloon for FETO that deflates spontaneously when placed in a strong magnetic field, therefore overcoming the need for a second procedure. The safety and efficacy of this device have not yet been demonstrated. The aim of this study was to investigate the reversibility, local side effects and occlusiveness of the Smart‐TO balloon, both in a simulated in‐utero environment and in the fetal lamb model.
