Abstract
Oppfinnelsen vedrører en innretning for temporær lukking av en kroppskanal, spesielt for assistering av hjertefunksjonen ved anvendelse av mottrykk. Innret- ningen er kjennetegnet ved at den omfatter en første oppumpbar struktur (1) som i oppumpet tilstand avgrenser en hylse formet til å tilsvare den indre overflate av kanalen og tilveiebringer en sentral gang (4). Innretningen omfatter ytterligere en andre oppumpbar struktur som utvider seg radielt, foretrukket fra det ytre til det indre, holdes av den første struktur (1) og er formet slik at den i oppumpet tilstand tillater hovedsakelig fullstendig lukking av den sentrale gang (4) dannet etter oppumping av den første struktur. Innretningen omfatter endelig midler for å la hver av disse første og andre oppumpbare strukturer være i fluidkommunikasjon med en kilde for fluidtilførsel.
