Frequently Asked Questions

The Seraph^® 100 Microbind^® Affinity Blood Filter (Seraph 100) is a single-use broad-spectrum extracorporeal hemoperfusion device that is in development for use as an adjunctive treatment of bloodstream infections.

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.
