Self-regulating device for modulating inflammation

A bioreactor is provided which contains cells capable of producing cytokine inhibitors in response to cytokines, in a manner regulated by the local or systemic milieu of an individual patient and predicted by mechanistic computational simulations. The bioreactor transfers the cytokine inhibitors to a patient in need of control of the inflammation process as part of a disease or condition in the patient, such as sepsis, trauma, traumatic brain injury, or wound healing. Related methods also are provided.

PERFUSION BIOREACTOR, PERFUSION DEVICE, ARTIFICIAL LIVER SYSTEM, AND RELATED METHODS

A perfusion bioreactor and a perfusion device. Each perfusion device has a mesh structure, and an encapsulated organ tissue (EOT) disposed in the mesh structure. The EOT has a body with a thickness defined between a first surface of the body and a second surface of the body. The body has at least one channel extending into the body from one of the first and second surfaces to receive a fluid therein. The at least one channel has a diameter selected to diffuse solutes out of the fluid and into the body. The perfusion devices are arranged one adjacent to another and spaced apart from each other along the length of the bioreactor to receive fluid, and to perfuse the fluid to the EOT of each perfusion device and to the at least one channel therein. A method of processing blood plasma and an artificial liver system are also disclosed.

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.

Cartridge and method for increasing myocardial function

The present invention relates to a cytopheretic cartridge for use in treating and/or preventing inflammatory conditions that affect myocardial function and to related methods. The cartridge can be used in treating a subject with myocardial dysfunction, such as a subject with chronic heart failure and/or acute decompensated heart failure.

BIOREACTOR AND BIOLOGICAL REACTION SYSTEM
20220218887 · 2022-07-14 ·

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.

Bioartificial liver based on human iPSCs-derived hepatocyte-like cells and multilayer porous bioreactor

A bioartificial liver (BAL) based on human induced pluripotent stem cells (iPSCs)-derived hepatocyte-like cells (HLCs) and a multilayer porous bioreactor is provided. The plasma separation/retransfusion loop part includes a blood input pipe, an exhaust pipe spring clamp, a blood input peristaltic pump, a heparin pump, a plasma separation column, a first pressure monitor, and a heater. The cell reactor/plasma component exchange double-loop part includes a plasma input peristaltic pump, and a semipermeable membrane exchange column, a plasma exchange peristaltic pump, a red blood cell (RBC) pool, a membrane lung, a multilayer porous bioreactor, a second pressure monitor, and a third pressure monitor arranged in a 37° C. dedicated incubator. An outlet of the third pressure monitor and a blood cell outlet are connected to an inlet of the first pressure monitor, and then connected to the heater and a blood output pipe in sequence.
