20090156976 | Devices and Methods for Extracorporeal Ablation of Circulating Cells - Methods and devices are provided for the extracorporeal ablation of target cells circulating in blood of an organism. Exogenous material introduced into the blood preferentially associates with target cells (e.g. cancer cells, bacteria, viruses) in the blood. An extracorporeal continuous flow pathway accesses the patient's blood to apply an external energy source to the blood at an ex vivo ablation device in a portion of the extracorporeal continuous flow pathway. The exogenous material interact with the applied energy so as to result in the damage or death of the target cells. The blood is then returned to the body in a continuous-flow pattern. By applying the energy while the blood is in the ex vivo ablation device, shielding of the target cells by the body is reduced and detrimental effects on the organs and tissues of the body are avoided or mitigated. | 06-18-2009 |
20090281473 | Anti-Human Immunodeficiency Virus Surrogate Target Agent Technology Filter Intended to Neutralize or Remove Human Immunodeficiency Virus Virions From Blood - The Human Immunodeficiency Virus posses a significant threat to the world's population. Current strategies utilized to treat infectious agents have not been adequate to contain and eradicate this deadly viral infection. HIV seeks out its host, a T-Helper cell, by utilizing glycoprotein 120 probes to engage a CD4 cell-surface receptor located on the surface of a T-Helper cell. Developing blood filtering techniques that incorporate filter mediums that offer HIV virion's probes the opportunity to engage the cell-surface receptors they are seeking offers a means of neutralizing and removing HIV. Filtering the blood of a patient with filter mediums comprised of T-Helper cells, sheets of lipid bilayer or virus-like structures with each type of medium possessing cell-surface receptors intended to attract and engage HIV virions provides an effective strategy to prevent and treat AIDS. | 11-12-2009 |
20090292233 | ANTI-HUMAN IMMUNODEFICIENCY VIRUS SURROGATE TARGET AGENT TECHNOLOGY FILTER INTENDED TO TERMINATE T-HELPER CELLS INFECTED WITH THE HUMAN IMMUNODEFICIENCY VIRUS CIRCULATING IN BLOOD - The Human Immunodeficiency Virus posses a significant threat to the world's population. Current strategies have not been adequate to contain and eradicate this deadly viral infection. HIV utilizes a T-Helper cell as a host to generate replicas of itself. Reversing HIV's own biologically deadly tactics and developing blood filtering techniques that incorporate filter mediums that engage the cell-surface receptors uniquely located on the surface of a T-Helper cell infected with the HIV genome can lead to terminating the infected T-Helper cells. Filter mediums possessing cell-surface receptors intended to terminate infected T-Helper cells by triggering apoptosis, is an effective means to eliminate HIV's host cells and thus provides a valuable strategy to prevent and treat AIDS. Similar techniques can be utilized to terminate other types of cells that act as hosts for pathogens as well as terminating cancer cells. | 11-26-2009 |
20100069814 | SYSTEM AND METHOD FOR UTILIZING MICROBUBBLES AND LIPOSOMES AS VIRAL SEQUESTERING AGENTS - A system and method of utilizing microbubbles and liposomes as viral sequestering agents. Microbubbles and liposomes having polyanions and conjugation systems are injected into the bloodstream of a subject human or animal. The microbubbles and/or liposomes attract virus particles including envelope viruses. After the microbubbles and/or liposomes have circulated in the blood for a pre-established time period, the microbubbles and/or liposomes along with attached virus particles are separated from the blood of the subject by passing the blood over or through a substrate or using a centrifuge. The substrate includes a conjugation system which has an affinity for the polyanions of the microbubbles and/or liposomes. As the microbubbles and/or liposomes and attached virus particles are removed from the blood, the viral titer of the subject is lowered. The microbubbles and/or liposomes may also be mixed with blood and filtered outside of the subject such that the microbubbles and/or liposomes are never in the bloodstream of the subject. | 03-18-2010 |
20100069815 | SUBSTRATE FOR BIOLOGICAL FLUID TREATMENT - It is an object of the present invention to provide a practically applicable substrate for blood treatment for specifically capturing a target substance such as a cell directly from the whole blood, and an inexpensively and industrially applicable substrate for biological fluid treatment which is capable of separating a target substance directly from a biological fluid. The present invention provides a substrate for biological fluid treatment in which a recognition molecule having a selective binding property for a target substance is covalently immobilized on a surface of the substrate, wherein the recognition molecule is a linear molecule comprising a ligand moiety and an association domain, and at least four or more recognition molecules form an assembly structure. | 03-18-2010 |
20100331753 | A Blood Purification Method and Apparatus for the Treatment of Malaria - Methods for treating malaria are provided, the treatment comprising the step of removing malaria-infected red blood cells from the patient s blood. Blood is drawn from the patient s circulatory system and circulated through a blood purification device that selectively eliminates the infected red blood cells from all other blood s components and replaces the cleansed blood back into the patient s circulatory system. A blood purification device, which is useful to perform the therapeutic methods of the invention, is also provided. The device leverages the magnetic properties of the hemozoin contained within the infected red blood cells and comprises one or more separation chambers ( | 12-30-2010 |
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 |
