Reference_Aid_programme: SA.41471(2015/X) Purpose_public_aid: Article 25 of Regulation (EC) No 651/2014 of 17 June 2014 declaring certain categories of aid compatible with the internal market in application of Articles 107 and 108 of the Treaty (OJ Urz. EU L 187/1 of 26.06.2014). Acute aortic dissection is one of the most serious life-threatening conditions. It runs very dynamically, manifesting itself in patients with rupturing chest pain. Requires immediate and accurate diagnosis and immediate surgical treatment. Unfortunately, the mortality rate in people who are not subjected to it quickly enough is more than 50 % within the first 48 hours of its occurrence. There are currently no devices to securely extend the period between acute aortic delamination and life-saving surgical treatment. The aim of the project is to change this state of affairs by developing and implementing an innovative medical device — Lifebuoy device. It will be like an “intravascular bandage” placed in the patient’s body for a period of 1 to 7 days, preventing aortic cracking. The effects of the project will be groundbreaking — the Lifebuoy device will significantly reduce mortality in people with acute aortic dissection, by extending the period of time that doctors need to prepare and conduct surgery. The applicant — Polimed, has several spectacular successes in the commercialisation of medical devices, including, for example, the device used in the procedures of the epidermal closure of the left vestibule of the heart (rights to it were purchased for $390 million). The design team, consisting of world-class specialists, including, among others, the inventor M. H. Akpinar, who is the author of several patents and patent applications, has often had the opportunity to cooperate with each other with success. [...]
