An apparatus for performing cerebral micro-dialysis to treat neurological disease of a patient's brain includes a catheter for implantation in or near the patient's brain, an implantable pump communicated with the catheter to transport cerebrospinal fluid (CSF) from the patient, which CSF contains diseased cells or biomolecules associated with the neurological disease, and an implantable separation device communicated with the pump wherein the diseased cells or biomolecules are removed, where the separation apparatus includes a dialysis membrane impregnated with an antibody, a reversible electrostatic filter, and/or a magnetic field effect fractionation chamber wherein a magnetically-tagged antibody scavenges and aids in the removal of circulating diseased cells or biomolecules from the CSF.

Described herein is a safety system that works collectively with an automated fluid drain control apparatus and systems and clinical experts to establish protocols and methods for given patient populations to ensure that the drainage of fluid from patients is both safe and effective. It further enables the transportation of drain orders from systems external to the drain system and returns to them the drainage data on a periodic basis for inclusion into the patient chart.

The disclosed systems and methods are configurable central nervous system (CNS) delivery solutions for therapeutics, such as genetic medicines. The systems and methods first infuse a therapeutic bolus within intrathecal space and subsequently infuse a flush fluid to move the therapeutic bolus rostrally toward a target area and achieve a desired spread in the spine and/or brain. The second location can be at a location caudal to the delivery location of the therapeutic bolus.

Described herein is the use of CSF, more particularly external CSF or CSF-like compositions for the treatment and prevention of different diseases. More particularly, the application provides for the administration of CSF to the intrathecal space or the cerebral ventricles of a patient to increase intracranial pressure and/or CSF flow.

The present disclosure generally relates to a system for flowing a fluid, e.g., CSF, from a body of a patient for sampling and analysis. In some embodiments, the system can include a diagnostic module having one or more conduits for flowing fluid therethrough. The flow of the fluid through the valves can be regulated using a control board that changes an orientation of valves disposed in the conduits between a dead-end orientation and a flow-through orientation to sample and/or analyze the fluid from the system. In some embodiments, the fluid can be recirculated into the system through one or more of the valves, with sampling and recirculating occurring substantially simultaneously.

Provided herein are materials and methods of reducing contamination in a biological substance or treating contamination in a subject by one or more toxins comprising contacting the biological substance with an effective amount of a sorbent capable of sorbing the toxin, wherein the sorbent comprises a plurality of pores ranging from 50 Å to 40,000 Å with a pore volume of 0.5 cc/g to 5.0 cc/g and a size of 0.05 mm to 2 cm and sorbing the toxin. Also provided are kits to reduce contamination by one or more toxins in a biological substance comprising a sorbent capable of sorbing a toxin, wherein the sorbent comprises a plurality of pores ranging from 50 Å to 40,000 Å with a pore volume of 0.5 cc/g to 5.0 cc/g and a size of 0.05 mm to 2 cm and a vessel to store said sorbent when not in use together with packaging for same.

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.

A dopamine or drug/therapeutics delivery and monitoring system for treatment of brain disease having an implantable titrator connected to the brain, a microtube for delivery of dopamine, a second microtube for withdrawal of CSF, a micropump for controlled pumping of dopamine into the brain responsive to sensed dopamine levels in the withdrawn CSF and a mixing chamber in the implantable titrator to combine withdrawn CSF with dopamine from a reservoir in the titrator to form a mixture for controlled delivery of the mixture. The system may have a fiber optic implanted and dopamine sensor responsive to certain sensed wavelengths of light received by a microcontroller. The system further has a dopamine reservoir and a carbon fiber resistance probe and may use fast scan cyclic voltammetry. A needle memory alloy having a straight and curved phase can be deployed into a blood vessel of a vascular system for trans-vascular delivery.

An embodiment provides a method for treating a body fluid, including: removing the body fluid from a patient; applying a treatment to the body fluid, wherein the treatment comprises an antibody that joins with an antigen in the body fluid to form an antibody-antigen complex; removing the antibody-antigen complex from the body fluid; and returning the body fluid to the patient. Other aspects are described and claimed.

A transcranial fastening device (1) for a drainage catheter (3), comprising an external body (5) being equipped with a passage (P), the passage (P) being equipped with blocking means (9) of the drainage catheter (3) adapted to allow a sliding of the drainage catheter (3) through the passage (P) along a first movement direction (M1) and to prevent a sliding of the drainage catheter (3) through the passage (P) along a second movement direction (M2).
