Hemostats can enhance clot formation and help to achieve hemostasis by controlling or preventing troublesome bleeding during surgical interventions where conventional methods of hemostasis are ineffective.

Hemostats
BD hemostats come in various forms that all help accelerate natural clot formation in many surgical applications. They facilitate use with features such as preloaded applicators and ready-to-use designs.
- Overview
- FAQs
BD offers a comprehensive range of hemostat products in a variety of formats to help surgeons address different types of bleeding that occur in a wide range of surgical procedures.

● Avitene™ MCH: Avitene™ is an absorbable topical hemostatic agent prepared as a dry, sterile, fibrous, water insoluble partial hydrochloric acid salt of purified bovine corium collagen. It is prepared in multiple forms including a loose fibrous flour, a compacted “non-woven” web form, and a collagen sponge.
● Arista ™ AH: This technology incorporates hydrophilic, flowable, microporous particles synthesized by cross-linking purified plant starch through a proprietary process; Arista™ AH is a 100% plant-based polysaccharide. Arista™ AH contains no animal or human components. Arista™ AH is a fine, dry, sterilized white powder that is biocompatible, non-pyrogenic, and is typically absorbed within 24 to 48 hours.
Different types of hemostats control bleeding in various ways.
● Avitene™ MCH: Avitene™ effectively enhances platelet aggregation and the release of proteins to form fibrin, resulting in hemostasis.
● Arista™ AH: The power of Arista™ AH lies in its proprietary MPH™ (microporous polysaccharide hemospheres) technology. Consisting of microporous particles with a controlled pore size, the spheres are designed to act as a molecular sieve. The powerful osmotic action dehydrates and forms a gelled matrix to enhance the natural clotting process.
Hemostats are often used in surgery to achieve hemostasis. For Arista™ AH, this can include:
● Cardiothoracic
● Cardiovascular
● Vascular
● Gynecological
● Urology
● Orthopedic surgery
● General surgery
● Plastic surgery
● Ear, nose and throat (ENT) surgery
Use of Arista™ AH in neurological or ophthalmic surgical procedures is excluded from its approved indication.
Avitene™ can be used in any surgical procedure where a topical hemostat can be used.
● Please note: Avitene™ Ultrafoam and MCH can be used in any surgical specialty other than ocular.
Hemostasis is important for surgeons, when trying to control bleeding during surgery. Surgeons should consider the wound and the type of surgery when selecting a hemostat. Understanding each kind of hemostat can help surgeons achieve the best outcome.
