Abstract
The invention concerns biocompatible polymer systems comprising at least one polymer with a plurality of pores, said polymer comprising either polyol or zwitterionic groups designed to adsorb endotoxins and other inflammatory mediator molecules. The inventions are in the field of porous polymeric sorbents, also in the field of broadly reducing endotoxins in blood and blood products that can cause endotoxemia, additionally, in the field of broadly removing endotoxins by perfusion or hemoperfusion.
