APHERESIS OF WHOLE BLOOD
20230123338 · 2023-04-20 ·

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.

DEVICES AND METHODS FOR TREATING A CORONAVIRUS INFECTION AND SYMPTOMS THEREOF

The devices and methods of the present invention can be used to capture and remove COVID-19 mediating nanoparticles and/or exosomes associated with COVID-19 or similar disease from the circulatory system of patients in need thereof, including those with post-COVID-19 syndrome or similar post-disease sequelae so-called “long haul” symptoms of COVID-19 or similar disease. The present invention benefits patients by providing lectin based extracorporeal methods for binding and physically removing SA RS-C7oV-2 virions, or fragments thereof, from the circulatory system. Also provided are lectin based extracorporeal methods of binding and physically removing non-viral COVID-19 mediating nanoparticles. Also disclosed herein are devices and methods for reducing the levels of biomarkers and markers of morbidity/mortality of diseases such as COVID-19 and similar diseases, including cytokines, such as IL-6, Troponin T, and D-dimer.
