Abstract

Det er beskrevet en kateteranordning og en seksjon (100) av en kateteranordning. ¿ Kateteranordningen kan anvendes for å få tilgang til et vevsmål inne i legemet, spesielt et mål som er tilgjengelig gjennom det vaskulare system. Sentralt for oppfinnelsen er anvendelse av et flettet, metallisk, forsterkende legeme (206), typsk av superelastisk legeringsbånd anbragt inne i kateterlegemet på en slik måte at det danner et kateter med l en eksepsjonelt tynn vegg, kontrollert stivhet, høy motstand mot brekking og fullstendig gjenvinning in vivo fra brukne situasjoner. Flettingen kan ha en enkel stigning eller kan : ha en varierende stigning langs aksen til kateteret eller kateterseksjonen. Det flettede, forsterkende båndlegemet (206) er typisk anbragt mellom et fleksibelt ytre rørlegeme (202) og et indre rørlegeme (204) for å danne en kateterseksjon som er meget fleksibel, men allikevel meget bøyebestanddig. Kateterseksjonene fremstilt i henhold til opp- finnelsen kan anvendes alene eller i forbindelse med andre kateterseksjoner, enten fremstilt ved anvendelse av konseptene beskrevet her, eller fremstilt på andre måter. De i mer proksimale seksjonene til kateteranordningen er ofte betydelig stivere enn de mer i distale seksjonene; på grunn av nærværet av stive polymerrør eller metalliske rør eller l komposittmaterialer i den stivere seksjonen.
