Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. The method may include the steps of withdrawing fluid comprising CSF, filtering the volume into permeate and retentate by passing the fluid through a tangential flow filter, and returning the permeate to the subject. During operation of the system, various parameters may be modified, such as flow rate.

Tangential flow filter system for the filtration of materials from biologic fluids

Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. In an example, CSF is separated into a permeate and retentate using a tangential flow filter. The retentate is filtered again and then returned to the subject with the permeate. During operation of the system, various parameters may be modified, such as flow rate and waste rate.

Systems and methods for treating biologic fluids are disclosed. Some disclosed embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject, heat CSF to a target temperature, cool CSF to a target temperature, apply light treatment to CSF, separate cells via their dielectric properties, apply spiral and/or centrifugal separation, introduce additives to target particles, and/or apply combinations thereof. The method may include the steps of withdrawing fluid comprising CSF, treating the fluid, and returning a portion of the treated fluid to the subject. During operation of the system, various parameters may be modified, such as flow rate.

Systems and methods for the conditioning of cerebrospinal fluid

Disclosed embodiments include methods and devices for introducing a sheath into a human or animal subject. Some embodiments include a puncture tool that may simultaneously deliver a sheath and a needle to a desired anatomical location. The needle may be removed and the sheath may be used to define a space that may be used to conduct a procedure.
