BrainCool AB will provide the RhinoChill System with all necessary accessories for use in the PRINCESS2 trial. The equipment will be delivered directly from BrainCool AB once the site has been enrolled into the study. If, at any time during the clinical study, a device becomes unserviceable, the clinical research team from that site will contact the BrainCool study support team, who will arrange collection of the device and swap it for a replacement device. At the conclusion of the study, members of the research support team at each site will collect all the equipment and inform BrainCool to arrange for collection.
