Title
(EN) INTRAVASCULAR DEVICE WITH ENHANCED ONE-BEAM CUT PATTERN
(FR) DISPOSITIF INTRAVASCULAIRE À MOTIF DE COUPE À UN SEUL FAISCEAU AMÉLIORÉ
Abstract
(EN)
Disclosed are intravascular devices having enhanced one-beam cut patterns. An elongated member includes a plurality of fenestrations that define a plurality of axially extending beams interspersed between a plurality of circumferentially extending rings. The beams are formed using a dual-pass cutting method in which a blade makes two, rotationally offset cutting passes at a given longitudinal location of the elongated member. The resulting beam has enhanced structure that avoids overly sharp edges and minimizes structural weak points.
(FR)
L'invention concerne des dispositifs intravasculaires ayant des motifs de coupe à un seul faisceau améliorés. Un élément allongé comprend une pluralité de fenêtres qui définissent une pluralité de faisceaux s'étendant axialement intercalés entre une pluralité d'anneaux s'étendant de manière circonférentielle. Les faisceaux sont formés à l'aide d'un procédé de coupe à double passage dans lequel une lame effectue deux passes de coupe décalées en rotation à un emplacement longitudinal donné de l'élément allongé. Le faisceau résultant présente une structure améliorée qui évite des bords trop nets et réduit au minimum les points faibles structurels.
