Inspiration Healthcare Group PLC (LON:IHC) said clinical testing is formally underway of the respiratory device it has designed for use in neonatal intensive care known as Project WAVE.
The technology is being used to treat a newborn at the Trevor Mann Baby Unit, Brighton & Sussex University Hospital.
Chief executive Neil Campbell said: "This is really exciting news. The first patient to be recruited on the trial is a real milestone for us and we eagerly await to see how the trial progresses.
“We continue to talk to other research groups about their interest and to refine the device as we develop our commercial strategy."
Inspiration acquired the technology for Project WAVE under a licence agreement in 2018 from the University of California Los Angeles.
It has developed it further to produce a patented device that is non-invasive and designed to reduce intermittent hypoxia in the newborn.
The project was granted a US patent last March.
