Abstract

Dette er en komposittføringsvire (102, 106) til bruk i et kateter. Den anvendes i medisinske prosedyrer der det skal skapes tilgang til bestemte målområder i et legeme uten store kirurgiske inngrep. Komposittføringsviren (102,106) er særlig hensiktsmessig for å skape adgang til målområder i perifere bløte vev. Føringsviren (102, 106) kan være en flerdelt føringsvireanordning som fortrinnsvis har forsterkninger (132) i form av flettede bånd av superelastisk legering over i det minste en del av kjernen (130). Føringsvirekjemen kan være av et rustfritt stål eller en høyelastisk metallegering, fortrinnsvis en Ni-Ti-legering. En variant av føringsviren (102, 106) kan også fortrinnsvis innbefatte en fletning (132) på utsiden av kjerneviren (130) med et utvendig polymert belegg (116) til den ytterste del (104) av anordningen og fortrinnsvis være sammensatt ved bruk av klebemidler, som for eksempel epoksier.
