Frequently Asked Questions

As blood flows through the Seraph filter, it passes over microbeads coated with molecular heparin receptor sites that mimic the heparan sulfate receptors on human cells that pathogens attack when invading the body. These harmful pathogens bind to the Seraph beads and are removed from the bloodstream.
