PROCESSING BLOOD

Methods (300), devices, and systems of processing blood are described. The method (300) comprises the steps of: obtaining (312) blood from a patient coupled to a single blood processing device to form a closed loop between the patient and the blood processing device; collecting (314) bulk mononuclear blood cells from the blood by leukapheresis implemented using the blood processing device in the closed loop; and enriching (316) concurrently target cells separated from non-target cells in the bulk mononuclear blood cells using the blood processing device in the closed loop.

Blood Treatment With Inactivation Of Circulating Nucleic Acids

The present invention relates to a device for the treatment of blood comprising a solid phase on which a polypeptide is immobilized which is suitable for the inactivation of free nucleic acids. Suitable polypeptides are, for example, deoxyribonucleases, ribonucleases, DNA methyltransferases or cytosine deaminases. The invention further comprises the use of such devices for the treatment of patients suffering from chronic kidney failure, cancer or lupus erythematosus, as well as methods and systems for the treatment of blood, wherein free nucleic acids are inactivated outside the body.

Blood processing apparatus and method for detoxifying bacterial lipopolysaccharide in vivo
12070543 · 2024-08-27 · ·

A detoxification method for treating sepsis, microbial infections, and other inflammatory conditions includes the steps of inducing flow of patient blood through a blood treatment device consisting of a bioreactor inlet and outlet in fluid connection to the circulatory system of a patient. Biological agents including lipopolysaccharide (LPS) and extracellular adenosine triphosphate (ATP) contained within patient blood can be irreversibly detoxified by passage of patient blood over a bioreactor surface having attached or immobilized alkaline phosphatase enzymes and acyloxyacyl hydrolase enzyme, with the bioreactor being contained within the blood treatment device. The method uses continuous treatment of a patient's blood to convert LPS and extracellular ATP in blood into inhibitors of inflammation in vivo without adding any chemicals to the bloodstream of the patient.

Blood processing apparatus and method for destroying cancer metastasis in vivo
12070541 · 2024-08-27 · ·

A blood treatment method includes the steps of inducing flow of a patient's blood through a blood treatment device inlet and outlet in fluid connection to the circulatory system of the patient. Metastatic deoxyribonucleic acid (DNA) contained within patient blood is destroyed by passing a patient's blood over a bioreactor surface having attached or immobilized deoxyribonuclease 1 (DNase 1) enzyme. The blood treatment device which consists of a bioreactor containing immobilized DNase 1, enables continuous treatment of a patient's blood and increases the effective concentration of DNase 1 in a patient's bloodstream to convert metastasizing cancer DNA in blood into non-oncogenic nucleotide fragments in vivo without adding any chemicals to the blood of the patient.

SYSTEM AND METHOD FOR ELECTROCHEMICALLY FILTERING A BODILY FLUID IN THE TREATMENT OF ALZHEIMERS DISEASE AND OTHER DISEASES
20240261486 · 2024-08-08 ·

A method for electrochemically filtering a bodily fluid in the treatment of a disease includes a pump to circulate the fluid through a collection container and an electromagnetic charging system. One of the cathode and anode leads is connected to a collection plate while the other of the cathode and anode leads is connected a patient to be treated. Inlet and outlet catheters are connected to patient to be treated. A predetermined voltage is applied across the anode lead and the cathode lead from a DC power supply, wherein circulating fluid from the patient passes through the collection container for removal of charged biological materials onto the collection plate. The fluid is returned back to the patient by the pump system.

20180326143 · 2018-11-15 ·

Devices, systems, or methods are disclosed herein for treatment of disease in a vertebrate subject. The device can include a quasi-planar substrate; and one or more laterally-mobile effector molecule types at least partially embedded within the quasi-planar substrate, wherein the one or more laterally-mobile effector molecule types is configured to interact with one or more cell types. The device can further include one or more sensors configured to detect at least one aspect of an interaction between the at least one of the one or more laterally-mobile effector molecule types and the one or more cell types; and a controller in communication with the one or more sensors, wherein the controller is configured to responsively initiate modification of at least one of the one or more laterally-mobile effector molecule types, the quasi-planar substrate, and the one or more cell types.

Bioartificial ultrafiltration device and methods related thereto

Bioartificial ultrafiltration devices comprising a scaffold comprising a population of cells enclosed in a matrix and disposed adjacent a plurality of channels are provided. The population of cells provides molecules such as therapeutic molecules to a subject in need thereof and is supported by the nutrients filtered in an ultrafiltrate from the blood of the subject. The plurality of channels in the scaffold facilitate the transportation of the ultrafiltrate and exchange of molecules between the ultrafiltrate and the population of cells.

EXTRACORPOREAL BIOENGINEERED DUAL-CELL LIVER REGENERATION SYSTEM (EBDLR) AND BIO PURIFIER THEREFOR

An EBDLR system includes a multi-layered bio purifier having a plurality of layers. Each layer includes a membrane, a first type of cells on a first side of the membrane in a first channel, and a second type of cells on a second side of the membrane in a second channel. The EBDLR includes a plasma separator to receive blood from a subject and separate a plasma component from the blood, a first reservoir to collect the plasma component, and a second pump to move the plasma component from the first reservoir to the multi-layered bio purifier. The multi-layered bio purifier distributes the plasma component into the first and second channels of each layer to purify the plasma component. The EBDLR includes a second reservoir to collect the purified plasma component and a third pump to infuse the purified plasma component from the second reservoir into the subject.

Bioreactor and biological reaction system

A bioreactor has a cover, a container body, a sealing portion, a driving portion and a liquid guide portion. A ventilation structure and a bacteria-retaining sealing breathable structure provided in the cover, a cleaning liquid inlet portion penetrates the bottom of the driving portion, and a liquid inlet portion and a liquid outlet portion of the liquid guide portion are arranged penetrating a sidewall of the container body. The driving portion drives, by means of elastic deformation, a liquid to be replaced or a cleaning liquid to move up and down, such that the liquid to be replaced can enter the container body only through a gas-liquid channel, so as to subsequently prevent damage to hepatic cells due to a carrier bearing a shearing force, and enable the liquid to be replaced to gain full contact with the carrier. Further provided is a bioreaction system.
