Abstract: Filtering cassettes, filtering systems, and methods for using the same are disclosed. An example filtering cassette may include a cassette housing. An inlet may be coupled to the cassette housing. The inlet may be configured to receive cerebrospinal fluid from a catheter. An outlet may be coupled to the cassette housing. The outlet may be configured to direct filtered cerebrospinal fluid to the catheter. One or more filters may be disposed within the cassette housing. An arcuate surface may be defined along a periphery of the cassette housing. The arcuate surface may be configured to engage a controller assembly when the cassette housing is mounted to the controller assembly.

Abstract: Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed. An example method may control operation of a pump of pump/filtration system to facilitate removing cerebrospinal fluid from a patient, filtering the cerebrospinal fluid with a filter module to remove waste product, and returning the filtered cerebrospinal fluid to the patient. Operation of the pump may be adjusted based on a value related to a measure sensed by a sensor in communication with a lumen carrying cerebrospinal fluid through the filtration system.

Abstract: Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed including sampling systems. An example sampling system may include a filter cassette designed to filter cerebrospinal fluid. The filter cassette may have an inlet region configured to be coupled to a catheter and configured to receive cerebrospinal fluid, one or more filters, and an outlet region configured to be coupled to an outlet of the catheter and to direct filtered cerebrospinal fluid to the catheter. A sampling port may be in fluid communication with the filter cassette. The sampling port may have a first end region configured to receive cerebrospinal fluid, a stopcock, a syringe port, and a second end region. The stopcock may be configured to shift between a first position where cerebrospinal fluid is directed from the first end region to the second end region and a second position where cerebrospinal fluid is directed from the first end region to the syringe port.
