Bioviva is an individually packaged, sterile, soluble, cellulose-based, bacteriostatic Hemostatic Gauze dressing made from oxidized, regenerated cellulose derived from plants. Bioviva absorbs blood and immediately transforms into a viscous gel, sealing the Extraction site, filling wound voids, seals capillary ends and activating the clotting system to assist the body to stop bleeding.
