The Hemopurifier is a single-use disposable cartridge designed for use with dialysis machines and other blood circulatory pumps. It functions to selectively remove harmful substances from the blood, giving a potential method of addressing diseases. During October 2014 the Hemopurifier was used as an adjunct in the treatment of a patient who was suffering from Ebola, who subsequently recovered.[53] The FDA has subsequently approved the device for testing in up to 20 infected Ebola cases in the United States.[54]
