Medafor's Arista AH Absorbable Hemostat has received FDA approval. In the U.S., this easy-to-use, efficacious and safe hemostat is indicated for most types of surgery including cardiac, orthopedic, spinal and general surgical applications. The surgical hemostat consists of Medafor's patented Microporous Polysaccharide Hemospheres, a plant-based, flowable powder engineered to rapidly dehydrate blood, enhancing clotting on contact. Arista AH facilitates the formation of a highly resilient, natural clot within just a few minutes regardless of the patient's coagulation status. The hemostat is instantly ready to use, requiring no mixing, no addition of patient blood or other components and no special handling or storage conditions.
