We aim to fill a vital treatment gap by providing non-invasive treatment and management-capacity of patients with elevated ICP with the aim of increase survival and reduce secondary brain injury. Treatment is envisioned to have use both for combat-training and battlefield related direct head-trauma or blast related injury. The treatment can be directly transferred to civilians for sports or accident related head-trauma as well as stroke. Combined, this novel device and method hold potential to overturn current treatment regime to increase survival and reduce secondary brain injury.
