Aroa Biosurgery is a New Zealand regenerative medicine company that produces extracellular matrix products derived from ovine forestomach tissue, used in wound care and soft tissue repair. Founded in 2008 and headquartered in Auckland, Aroa is distributed in South Africa by Dynamed Pharmaceuticals, a SAHPRA-registered supplier based in Durban.
The origins of Aroa Biosurgery
Aroa Biosurgery was founded in February 2008 by Dr Brian Ward, a veterinary surgeon who trained at Massey University. The company was originally named Mesynthes and began in Wellington before relocating to a purpose-built facility in Auckland in 2014.
The founding insight came from an unusual place. Ward was following developments in soft tissue regeneration and recognised two problems holding the field back: reliable access to source tissue, and the risk of disease transmission from animal-derived materials. He realised that the forestomach of sheep contains an extracellular matrix with a structure closely resembling human tissue, and that New Zealand's geographic isolation and disease-free national flock could supply that material safely and at scale.
What began as a low-value byproduct of the meat industry became the raw material for a regenerative medicine platform. The company filed its first patent covering ovine forestomach matrix in 2008, and the matrix was first described in the scientific literature in 2010.
What Aroa Biosurgery is recognised for
Aroa Biosurgery is recognised internationally for pioneering ovine forestomach matrix as a regenerative biomaterial, and for building a commercially successful medical device company out of New Zealand.
The company has been listed on the Australian Securities Exchange since 2020, when it floated at a valuation of A$225 million. It now employs more than 270 people across New Zealand and North America, holds regulatory approval in over 50 countries, and reports that more than six million Aroa products have been used in procedures worldwide.
Its first product, Endoform Natural, received clearance from the United States Food and Drug Administration in 2009 for the treatment of acute and chronic wounds. The company has since been recognised in New Zealand business awards for innovation, and its technology is widely cited as an example of high-value manufacturing built on a locally abundant raw material.
Aroa reports that its matrix contains more than 150 signalling molecules involved in the healing process, a complexity the company states cannot be reproduced synthetically.
The science of the extracellular matrix
The extracellular matrix is the scaffold that surrounds cells in living tissue. It is a network of collagen, proteins and signalling molecules that holds tissue together and directs where cells travel and what they do. In healing, this matters because new cells need something to attach to, migrate across and organise around. Without a functional matrix, repair slows or stalls entirely.
Chronic wounds illustrate the problem. In a wound that has stopped progressing, the local matrix is often damaged or broken down by enzymes faster than the body can rebuild it. An extracellular matrix dressing supplies a ready-made structural template in its place. Cells can populate it, blood vessels can grow into it, and the wound has a foundation from which to progress.
This differs from a simple collagen dressing, which supplies collagen without the surrounding architecture. It also differs from synthetic scaffolds, which are engineered polymers the body may treat as foreign. A biologically derived matrix aims to resemble the native tissue environment far more closely.
Ovine forestomach matrix: the platform
Ovine forestomach matrix is the core technology behind every Aroa Biosurgery product. Sheep forestomach tissue retains a complex, vascularised matrix structure, meaning it holds the natural channels where blood vessels once ran, alongside residual growth factors and a broad range of matrix proteins.
Manufacturing relies on decellularisation. This removes the cellular material that would trigger an immune response while preserving the three-dimensional architecture of the matrix itself. What remains is a structural template rather than living tissue.
The Aroa product range
Aroa Biosurgery produces several product lines built on the same ovine forestomach matrix platform, each shaped for a different clinical setting. The Endoform range serves open wound management, while the Myriad range addresses surgical and soft tissue applications.
Endoform Natural is a thin matrix sheet applied directly to the wound bed for chronic and acute open wounds, integrating as healing progresses.
Endoform Antimicrobial incorporates silver to help manage bioburden where infection risk is a concern.
Myriad Matrix is a thicker, layered graft for surgical soft tissue reconstruction and reinforcement, providing more substantial tissue volume than a dressing sheet.
Myriad Morcells Fine is a particulate form of the matrix, used to fill irregular contours and cavities that a flat sheet cannot reach.
Clinical applications
Aroa Biosurgery products are used across a range of complex presentations where standard care has not delivered progress. These include chronic wounds, diabetic foot ulcers and venous leg ulcers, all of which frequently resist conventional dressings.
On the surgical side, the technology is applied to soft tissue reinforcement and hernia repair, where a durable biological scaffold supports the surrounding tissue during recovery.
The practical advantage for clinicians is that a single platform covers several needs. A wound clinic managing a stubborn ulcer and a surgical team reinforcing a repair are drawing on the same underlying matrix science, adapted to the format that suits the case.
Choosing the right Aroa product
The most useful way to select an Aroa Biosurgery product is by clinical need rather than by product name. The table below groups the range by the situation in front of you.
| Clinical need | Suitable option | Format |
|---|---|---|
| Open wound management, standard use | Endoform Natural | Thin matrix sheet |
| Wounds where infection risk is present | Endoform Antimicrobial | Matrix sheet with silver |
| Surgical soft tissue reinforcement | Myriad Matrix | Layered graft |
| Irregular or tunnelling contours | Myriad Morcells Fine | Particulate matrix |
For standard open wound management, Endoform Natural is the usual starting point, while the antimicrobial version with silver suits wounds where bioburden is a concern. Where a surgical repair needs reinforcement, the Myriad soft tissue matrix provides greater volume than a dressing sheet, and the fine particulate format reaches cavities and tunnelling wounds a flat sheet cannot. You can view the full platform on the soft tissue regeneration range.
