Filter system and filter manifold for use with filter system

The invention discloses a filtering device for filtering cerebrospinal fluid. An example filtration 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 path therein between the inlet and the outlet. A filter section may be defined within the filter housing along the fluid path. The filtration section may include a widened region of the fluid path configured to slow passage of fluid therethrough. 本发明公开了用于过滤脑脊液的过滤装置。实例过滤装置可包括过滤器外壳，所述过滤器外壳具有入口和出口，所述入口用于从患者接收脑脊液，所述出口用于将所过滤的脑脊液返回至所述患者。所述过滤器外壳可包括多个层，所述多个层联接在一起并且在其中限定所述入口和所述出口之间的流体路径。过滤部段可沿着所述流体路径限定于所述过滤器外壳内。所述过滤部段可包括所述流体路径的加宽区域，所述加宽区域配置成减缓流体从中通过。
