Arista AH is a 100% plant based absorbable surgical haemostatic powder derived from purified plant starch. The power of Arista AH lies in its microporous polysaccharide hemospheres, a patented blood clotting technology. Arista AH is indicated in surgical procedures (except neurologic and ophthalmic) as an adjunctive haemostatic device to assist when control of capillary, venous, and arteriolar bleeding by pressure, ligature, and other conventional procedures are ineffective or impractical.
