Feedback shares rose 12% to 1.05p this week on news that Bleepa will now be used by the Royal Papworth Hospital NHS Foundation Trust as well.

“The launch of Bleepa at Papworth is further evidence of the changing needs of front-line clinicians around their interaction with medical imaging and with colleagues, something that we are uniquely positioned to enable,” said Feedback’s chief executive Tom Oakley.

The med-tech group has applied for a CE mark, which would provide European regulatory sign off for the device. Once this comes through, the plan is to distribute Bleepa across as many hospitals as possible.
