Abstract

Selv-utfoldbar aksialstrømningspumpe innrettet til å innføres intravaskulært for midlertidig gjeste-understøttelse el- ler -assistanse. Denne aksialstrømnings- pumpe beregnet for innføring gjennom en pasients åresystem har et fleksibelt, sammentrykkbart ror (1) som utgjør pumpe- huset. En radielt sammentrykkbar rotor (7) er anbragt i røret (1). Drivakselen (6) for rotoren (7) strekker seg gjennom et kateter (4) . Kateteret (4) kan trekkes inn i en dekkslange (5) sammen med røret (1) og rotoren (7).
