This could have huge implications for almost any viral-borne disease (including avian flu):

Aethlon Medical, a small San Diego biotech company, is developing a portable de-vice that removes viruses from blood. Known as the Hemopurifier, it filters not only smallpox but numerous other viruses, including Marburg and Ebola.

The Hemopurifier resembles a shrunken dialysis cartridge, the rolling-pin-size de-vice that purifies the blood of patients whose kidneys have failed. Both use a filter to remove toxins from blood. But unlike traditional dialysis, the Hemo-purifier also includes plant-derived antibodies, such as cyanovirin, that bind to a variety of viruses and eliminates them from the bloodstream. The plant solution can be modified to weed out even genetically engineered germs.
