KOVE is an implantable medical device that closes and secures the hole created by the endoscopes used to treat fetuses during pregnancy. By closing this hole, KOVE decreases dramatically the risk of preterm birth, which is the main obstacle for the development of those interventions. Treating fetuses in the maternal womb, during pregnancy, risks triggering premature birth. Fetoscopic interventions -- using surgical instruments in the womb -- damages the fetal membrane and cause early births in 80 percent of cases. Doctor in bioengineering, Yannick Devaud developed this technology at University Hospital of Zurich. This innovation may prevent membrane rupture following fetoscopies, opening the path to more fetal treatment and fewer deaths.
