Overview

The purpose of this study is to demonstrate the safety and performance of Oasis extracellular matrix (ECM) when used as a treatment for donor site wounds in the United Kingdom. Oasis ECM is commercially available for the treatment of partial and full-thickness skin wounds, including chronic wounds, wounds from trauma, and wounds that occur during surgery, such as donor site wounds. The ability of the Oasis ECM to promote the healing of donor site wounds will be evaluated in this study.

About 40 patients (20 in each arm) over 16 years old will be involved in this study at one center in the United Kingdom.
