Millipede Aspiration for Revaskularisaatio aivohalvaustutkimuksessa (MARRS)
Tutkimuksen yleiskatsaus
Yksityiskohtainen kuvaus
Iskeeminen aivohalvaus on hengenvaarallinen tila. Vuosittain noin 795 000 ihmistä Yhdysvalloissa saa aivohalvauksen.
MARRS-tutkimus on interventiotutkimus, avoin, yksihaarainen, monikeskustutkimus, prospektiivinen kliininen tutkimus. Tutkimuksen tavoitteena on arvioida Millipede Systemin suorituskykyä ja turvallisuusominaisuuksia potilailla, joilla on LVO:n aiheuttama akuutti iskeeminen aivohalvaus, sekä kirjata kliiniset tulokset.
