Arista™AH is indicated in surgical procedures as an adjunctive hemostatic device in the control of capillary, venous and arteriolar bleeding.

Arista™AH is a sterile, absorbable hemostatic powder consisting of Microporous Polysaccharide Hemospheres (MPH®), Medafor's patented clotting technology derived from purified plant starch.

When applied directly to the source of bleeding, Arista™AH begins clotting on contact, achieving complete hemostasis, in most cases, within minutes.

Position the Arista™AH applicator and apply powder to the bleeding site.

Unlike other surgical hemostats which claim to be "ready when you are" but which can require minutes to hours for preparation, Arista™AH requires:

• NO mixing
• NO additional components
• NO assembly
• NO special storage conditions

Arista™AH begins clotting on contact and achieves complete hemostasis in a matter of minutes. The flowable particles provide complete coverage on both rough surfaces and in small, hard-to-reach spaces.

Arista™AH is a natural composition synthesized from a purified plant polymer and free of all biological components. As such, it is non toxic, non irritating, non hemolytic and non mutagenic. Arista™AH reaches its maximum volume immediately upon contact with blood or other fluids. In clinical studies, Arista™AH has produced no adverse reactions. It is non immunogenic, fully biocompatible and readily absorbed in tissue in 24 to 48 hours.

Unlike other surgical hemostats, Arista™AH:

• is fully and safely ABSORBABLE – within 24 to 48 hours (min. absorption time for other surgical hemostats is typically 3-8 weeks)
• contains NO HUMAN OR ANIMAL components
• DOES NOT SERVE AS A NIDUS FOR INFECTION OR GRANULOMA FORMATION
• is ready INSTANTLY, requiring NO PREPARATION TIME
• is CELL SAVER COMPATIBLE
