a microporous polysaccharide hemostatic product that has a unique mechanism of action; the microspheres have a porous surface that effectively absorbs water and low-molecular-weight compounds from the blood and thus concentrates the platelets and clotting proteins on the surface of the vascular bed, thereby enhancing endogenous clotting mechanisms; made from purified potato starch and formed into 30 to 100 μm spheres with a microporous surface
