Abstract

Filtering device for filtering cerebrospinal fluid are disclosed. An example filtering device may include a filter housing having an inlet for receiving cerebrospinal fluid from a patient and an outlet for returning filtered cerebrospinal fluid to the patient. The filter housing may include a plurality of layers coupled together and defining a fluid pathway therein between the inlet and the outlet. A filtering section may be defined within the filter housing along the fluid pathway. The filtering section may include a widened region of the fluid pathway that is configured to slow the passage of fluid therethrough.
