Un alto nivel de proteínas o células tumorales en el LCR puede llevar a una obstrucción de la válvula. Estos temas fueron objeto de particular atención en el desarrollo de la válvula de Miethke DualSwitch. El diseño especial de la válvula presenta una superficie muy grande a la CSF, lo que garantiza un funcionamiento fiable incluso líquido incontaminado. Los estudios clínicos también demuestran el éxito del tratamiento de los pacientes con la llamada hidrocefalia de presión normal (NPH). La válvula de Miethke DualSwitch está hecha de titanio, un material que garantiza la precisión, fiabilidad y biocompatibilidad.
