The £25m North West Fund for Biomedical, which is managed by Spark Impact, is part of the £185m evergreen fund provided by the European Investment Bank (EIB) and European Regional Development Fund (ERDF).
The North West Fund for Biomedical Spark Impact manager and Senior Investment director Penny Attridge said AMD has some very specific targets and milestones to meet over the next 3-6 months which they are convinced there is now a team to deliver.
"From the interest and excitement Melio has received we are hoping the company will grow rapidly, achieve significant sales in a short period of time and be a great addition to the medical device community, while supplying a great return for its shareholders," Attridge said.
