Fetal aqueductal stenosis is the leading cause of congenital hydrocephalus and effects 2-4 infants per 10,000 births. The condition can currently be diagnosed via ultrasound as early as 20 weeks of gestation. However, no treatment is available until after birth, leading to increased risks of obstetric complications for the mother and long-term complications for the child. VASFAS is a shunt that will be placed in the fetus through the maternal abdominal wall under ultrasound guidance allowing for immediate treatment of hydrocephalus in-utero. A potential market of $140 million has been estimated and no other fetal shunts for hydrocephalus treatment are currently available on the market.
