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.

An implantable system for monitoring a hydration state of a patient and adjusting fluid removal from the patient includes a pressure sensor implantable within an inferior vena cava of the patient and a processor. The pressure sensor senses and generates an output representative of a baseline inferior vena caval pressure value of the patient and chronically senses and generates outputs representative of an inferior vena caval pressure value of the patient. The processor compares differences between the baseline inferior vena caval pressure value and subsequent inferior vena caval pressure values. The processor can reside in another implantable device or in an external device/system.
