BD haemostats come in various forms that all help accelerate natural clot formation in many surgical applications.


BD offers a comprehensive range of haemostat products in a variety of formats to help surgeons address different types of bleeding that occur in a wide range of surgical procedures.

Haemostat Basics 

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

● Arista ™ AH: This technology incorporates hydrophilic, flowable, microporous particles synthesised 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, sterilised white powder that is biocompatible, non-pyrogenic, and is typically absorbed within 24 to 48 hours. 

Avitene™ MCH: Avitene™ is an absorbable topical haemostatic 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.


How Haemostats Work 

Different types of haemostats control bleeding in various ways.

● Arista™ AH: The power of Arista™ AH lies in its proprietary MPH™ (microporous polysaccharide haemospheres) 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. 

Avitene™ MCH: Avitene™ MCH effectively enhances platelet aggregation and the release of proteins to form fibrin, resulting in haemostasis.

Haemostats are often used in surgery to achieve haemostasis. For Arista™ AH, this can include:

● Cardiothoracic

● Cardiovascular

● Vascular

● Gynaecological

● Urology

● Orthopaedic 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 haemostat can be used.

Please note: Avitene™ Ultrafoam and MCH is not for intraocular or intravascular use.

Haemostasis is important for surgeons, when trying to control bleeding during surgery. Surgeons should consider the wound and the type of surgery when selecting a haemostat. Understanding each kind of haemostat can help surgeons achieve the best outcome.
