Polymeric sorbent, preparation and use thereof
Polymer sorbents selectively remove cytokines and bacterial endotoxins from whole blood and other body liquids, in particular blood plasma, lymph etc., as well as from aqueous protein solutions and aqueous organic compound solutions, also containing inorganic salts. The sorbent is able to remove both cytokines and bacterial endotoxins, improve selectivity of the polymer sorbents in respect to the compounds as well as provide a simple and effective method of producing said sorbent.

TREATING MORBID OBESITY EXTRACORPOREALLY
An embodiment provides a method for treating a body fluid of a patient with morbid obesity, including: removing the body fluid from a patient; applying a treatment to the body fluid, wherein the treatment comprises an antibody that joins with a morbid obesity targeted antigen (TA) in the body fluid to form an antibody-TA complex, wherein the antibody comprises a tag sensitive to an illumination; removing the antibody-TA complex from the body fluid using an illumination source; and returning the body fluid to the patient. Other aspects are described and claimed.
Device and method for removing undesirable biological and/or chemical entities from biological fluids
A device removing a biological and/or chemical entity (C) from extracorporeal blood (B) is disclosed. The device has a hollow capture chamber with an inlet for the entry of the extracorporeal blood (B) and an outlet for the outflow of the extracorporeal blood (B) and a capture element inside the capture chamber having a reactant surface placed in contact with the extracorporeal blood (B) and a plurality of binding agents (A) for the biological and/or chemical entity to be removed (C) such that the biological and/or chemical entity (C), upon exiting the capture chamber, is removed from the extracorporeal blood (B) as linked to the reactant surface.
Porous fiber, adsorbent material, and purification column
A solid fiber is described, where the solid fiber is characterized by (a) a modification degree Do/Di, in a cross section of the solid fiber of 1.20 to 8.50 where the inscribed circle diameter is denoted by Di and the circumscribed circle diameter is denoted by Do; and (b) a porous specific surface area of not less than 30 m.sup.2/g.
Flow capture device and method for removing cells from blood
Flow capture device and method for removing cells from blood The current invention discloses a blood treating and/or purifying device for removing circulating pathogens, preferably pathogenic cells, more preferably circulating tumor cells from the blood of a patient, a method of producing such a device and method to treat cancer and other diseases caused by virus infection, bacterial infection and parasites infection as well as autoimmune disorders. The described method is an extracorporeal medical therapy, thus can be done also in a hemodialysis system. The current invention also describes a device and an in-situ production method of preparing the device to remove CTC and other pathogens i.e. virus, bacteria or parasites from the bloodstream.
Immunosuppressive protein adsorption material and adsorption column
An objective of the present disclosure is to provide an adsorption material that has a carrier material with retained physical strength, and efficiently adsorbs an immunosuppressive protein. The present disclosure provides an adsorption material for immunosuppressive protein. The adsorption material includes a water-insoluble carrier to which at least one nitrogen-containing compound selected from a polyamine represented by a predetermined formula and aliphatic amines represented by predetermined formulae is bound. A total content of amino groups on the water-insoluble carrier is more than 0 μmol and 2500 μmol or less per 1 g, and a content of primary amino groups on the water-insoluble carrier is 450 μmol or less per 1 g.
APHERESIS OF WHOLE BLOOD
A method for performing apheresis of mammals, including humans, is set forth which does not require separation of the blood into plasma or any other portion. Termed whole blood apheresis herein, this advance makes it possible to perform apheresis more quickly and efficiently with less stress for the patient. This application also discloses important advances in apheresis for therapeutic treatments, including treatments for sepsis and AKI using whole blood apheresis, and immunotherapy where targets that interfere with recovery are removed by apheresis and gene-engineered fragments previously removed are reintroduced. Use of selective withdrawal through apheresis expands possible resolutions of illnesses and conditions previously thought to be untreatable.
Recirculating fluid filtration system
A fluid filtration system comprising a cross-flow filter is arranged to permit a first pump to recirculate part of the retentate of the filter to the inlet of the cross-flow filter and a second pump to return part of the permeate to the inlet of the cross-flow filter. A third pump is configured supply source fluid to the inlet of the filter. The flow path between the second pump and the cross-flow filter inlet may include an adsorption filter that may selectively remove contaminants, toxins, or pathogens in the permeate. A controller may control the first, second and third pumps to provide predetermined flow ratios among the fluid flow paths of the system in order to achieve a desired filtration level. This system may be applicable to the removal of harmful substances from blood, by first separating the plasma from the blood and then removing harmful substances from the plasma.
