Beschreibung
Zusammenfassung:	An elongate medical device includes an elongate core and a substantially flat sheet formed into a tubular body defining a longitudinal axis and disposed around at least a portion of the elongate core, where the flat sheet has a length, and where a cross-sectional thickness of the sheet varies along the length of the sheet. The tubular body has proximal and distal portions, and a cross-sectional thickness of the sheet forming the distal portion of the tubular body may be less than a cross-sectional thickness of the sheet forming the proximal portion of the tubular body. A cross-sectional thickness of the sheet forming the tubular body preferably tapers from the proximal portion to the distal portion. L'invention concerne un dispositif médical allongé qui comprend un coeur allongé et une feuille sensiblement plate formée en un corps tubulaire définissant un axe longitudinal et placée autour d'au moins une portion du coeur allongé, la feuille plate ayant une longueur, et l'épaisseur de section transversale de la feuille variant sur la longueur de la feuille. Le corps tubulaire comprend des portions proximale et distale, et une épaisseur de section transversale de la feuille formant la partie distale du coeur tubulaire peut être inférieure à une épaisseur de section transversale de la feuille formant la portion proximale du corps tubulaire. Une épaisseur de section transversale de la feuille formant le corps tubulaire s'amoindrit de préférence de la portion proximale vers la portion distale.
