Polynovo earns most of its revenue from US sales of its NovoSorb Biodegradable Temporizing Matrix, or NovoSorb BTM. The product is a patented biodegradable synthetic scaffold to support the regeneration of the dermis when lost through surgery, trauma, burns, or other causes of tissue loss. Once the product is applied to a wound, it takes a few weeks for the dermal layer to fully integrate within the polymer scaffold before a clinician can delaminate the outer layer. A small wound would then close either naturally or with a dressing, while a larger wound would close through a split-skin graft or alternative product such as Avita's RECELL. NovoSorb BTM then slowly degrades to harmless byproducts which are fully absorbed in roughly 18 months.
