Abstract

Et kirurgisk instrument i form av en føringstråd bestående av en kjerne av rustfri stållegering som er belagt med en ikke-hydrofile, smørende polymer over hovedandelen av sin lengde lokalisert proksimalt og en hydrofil polymer lokalisert over hovedandelen av den gjenværende distale lengde av føringstråden. Fortrinnsvis er et polymerbindesjikt anordnet mellom metallkjernen av føringstrådenheten og det hydrofile polymersjikt. Metallkjernen er av et av et antall rustfrie stål for å kunne bevare sin moment-transmitterende evne. Fortrinnsvis er den utvendige diameter av føringstråden konstant fra den distale ende til den proksimale ende. Metallkjernen kan være trinnet ved egnede lokasjoner langs føringstrådenheten.
