Abstract: Disclosed herein are cerebrospinal fluid (CSF) circulation systems and devices. Also disclosed are methods of using the systems and devices for the processing of CSF and for the treatment of brain or central nervous system diseases, disorders, and injuries. In particular, CSF may be processed to remove various molecules targets, including viruses, bacteria, exosomes, cells, proteins, debris, toxins, and inflammatory mediators. CSF may also be warmed, cooled, and/or oxygenated, and medications or substances may be added to the CSF for targeted treatment of a disease or disorder.

Abstract: Devices, systems and methods for the broad-spectrum reduction of pro-inflammatory cytokines in blood. The pro-inflammatory cytokines can be freely circulating in the blood as well as cytokines that are transported within or bound to the surface of particles collectively referred to as CytoVesicles while simultaneously adsorbing toxins and pathogens from blood and blood plasma. A plasma separation column with binding, capture and adsorbent components optimize the removal of cytokines and CytoVesicles from blood while minimizing the removal of essential blood elements. Adsorbent components are incorporated within the extra-lumen space, outside of the plasma fiber walls and within the outer shell of the column and can include activated carbon, ion exchange resins and non-ionic exchange resins. The resulting devices, systems and methods alleviate the symptoms or severity of a wide range of disease conditions associated with an abnormal production or dysregulation of pro-inflammatory cytokines.

Abstract: An extracorporeal circuit for removing toxins from the blood and plasma volume control in patients suffering from sepsis and renal failure. The extracorporeal circuit disclosed herein comprises a plasma filter, a toxin removal device and optionally a hemofilter that minimizes electrolyte and protein depletion from the treated plasma while effectively removing both free and protein-bound toxins. The toxin removal device comprises adsorbent materials selected from the group consisting of activated carbon, ion exchange resins and non-ionic exchange resins and the adsorbent materials are coated with albumin. Also provided are associated methods for treating patients suffering from sepsis and renal failure using the disclosed extracorporeal circuit and toxin removal device.

Abstract: An endovascular system for arresting a patient's heart and maintaining the patient on cardiopulmonary bypass. A venous cannula, venting catheter and an aortic occlusion device are all coupled together so that the blood drawn into each of these catheters may be fed to a pump. A manifold has valves which control flows through the venous cannula, venting catheter and aortic occlusion device. A blood storage element is also provided so that the amount of blood in the perfusion circuit may be varied if necessary. The blood storage element is preferably positioned in parallel with the pump so that the pump may be used to add and remove blood to and from the blood storage element.

Abstract: A device for removing toxins from the blood of patients suffering from acute liver failure, acute-on-chronic liver failure and sepsis is provided. The toxin removal device disclosed herein comprises activated charcoal and at least one non-ionic resin for use in an extracorporeal circuit that minimizes electrolyte and protein depletion from the treated plasma. Also provided are associated methods for treating patients suffering from acute liver failure, acute-on-chronic liver failure and sepsis using the disclosed toxin removal device.

Abstract: A bone marrow infuser has an intraosseous cannula, a hand driver, and a pointed stylet attached to the hand driver. The hand driver can mechanically couple with the intraosseous cannula so that the stylet point protrudes from an opening at the end of the intraosseous cannula. A method of bone marrow infusion has a first step of puncturing the skin with the point of the stylet, a second step of embedding the cannula into the bone, a third step of removing the stylet from the cannula and attaching the catheter to the cannula, a fourth step of applying pressure to compress the skin, flesh, and bone, and a final step of infusing fluids into the bone marrow.

Abstract: A cannula assembly suitable for rapid, closed-chest cannulation of the cardiopulmonary system to an extracorporeal bypass machine through punctures in the femoral veins and arteries is disclosed. The assembly comprises a conduit made of a smooth, flexible, thin-walled material and capable of longitudinal insertion through these vessels by use of an associated "introducer" and conventional guide wire. The conduit has adequate hemodynamic flow capacity and sufficient unsupported hoop strength to resist collapse from suctional and vasoconstrictive forces during use.

Abstract: A closed emergency heart bypass system is disclosed herein for extra-corporeal blood circulation use which employs a minimum of components arranged in a series relationship. The components include a non-occlusive blood pump aspirating venous blood from an appropriate cannula for introduction to an oxygenator and a bubble-trapping device followed by return to a patient's body via an arterial cannula. Tubing interconnects the components and a bypass loop selectively joins the tubing adjacent to the venous and arterial cannulas for air displacement during initial pump priming and tube purging. Arterial blood can be accessed for sampling and for distal limb perfusion and a blood flow and monitoring console may be included in the system.
