Un alto livello di proteine o cellule tumorali nel liquor può portare al blocco della valvola. Tali questioni sono state oggetto di particolare considerazione nella definizione della valvola MIETHKE DualSwitch® . Lo speciale design della valvola presenta una superficie molto grande al CSF, garantendo così un funzionamento affidabile anche nel liquido contaminato. Studi clinici dimostrano anche la riuscita del trattamento di pazienti con il cosiddetto idrocefalo a pressione normale (NPH). La valvola MIETHKE DualSwitch ® è realizzata in titanio, un materiale che garantisce una precisione eccezionale, affidabilità e biocompatibilità.
