20090304677 | Extracorporeal Removal of Microvesicular Particles - The invention described herein teaches methods of removing microvesicular particles, which include but are not limited to exosomes, from the systemic circulation of a subject in need thereof with the goal of reversing antigen-specific and antigen-nonspecific immune suppression. Said microvesicular particles could be generated by host cells that have been reprogrammed by neoplastic tissue, or the neoplastic tissue itself. Compositions of matter, medical devices, and novel utilities of existing medical devices are disclosed. | 12-10-2009 |
20110009796 | METHOD AND APPARATUS FOR INCREASING CONTAMINANT CLEARANCE RATES DURING EXTRACORPOREAL FLUID TREATMENT - An extracorporeal fluid treatment apparatus includes a separator comprising a cartridge surrounding a porous separation membrane. The membrane separates a main flow path of a cellular component of the blood from a plasma flow path. An affinity medium is disposed within the plasma flow path to bind contaminants such as viral pathogens or toxins contained within the plasma. A pump pumps the plasma through the affinity medium at an assisted flow rate preferably between 10% and 40% of the whole blood flow rate. The assisted flow rate is selected to reduce a T90% of the apparatus by at least 50% as compared to a T90% of the apparatus without the plasma pump. A method of treating blood containing contaminants includes supplying infected blood to a separator and pumping the plasma component through an affinity medium at an assisted flow rate to increase contaminant clearance. | 01-13-2011 |
20110218512 | ENHANCED ANTIVIRAL THERAPY METHODS AND DEVICES - Embodiments of the present invention relate to enhanced antiviral therapy methods, devices, and kits for treating viral infections. The disclosed enhanced antiviral therapy methods, devices, and kits enhance the efficacy of an antiviral therapy by administering a lectin affinity hemodialysis treatment to an individual suffering from viral infection in combination with the antiviral therapy. | 09-08-2011 |
20110284463 | DEVICE AND METHOD FOR PURIFYING VIRALLY INFECTED BLOOD - The present invention relates to a method for using lectins that bind to pathogens having surface glycoproteins or fragments thereof which contain glycoproteins, to remove them from infected blood or plasma or other fluids in an extracorporeal setting. Accordingly, the present invention provides a methods and devices for reducing viral load or plaque forming units in blood or plasma from one or more infected individuals. A preferred embodiment of the method comprises passing the blood or plasma through a porous hollow fiber membrane wherein lectin molecules are disposed proximate to the membrane, collecting pass-through blood or plasma and optionally reinfusing the pass-through blood or plasma into the individual. Additionally, the present invention provides a methods and devices for the reduction of plaque forming units, cleared more rapidly and more efficiently than overall viral load. | 11-24-2011 |
