Title
(EN) ENDOLUMINAL PROSTHESES INCLUDING MULTIPLE HELICAL WIRES
(FR) PROTHÈSES ENDOLUMINALES COMPRENANT DE MULTIPLES FILS HÉLICOÏDAUX
Abstract
(EN)
A prosthesis includes a first wire bent into a first waveform and spirally wrapped into a first helix having a plurality of windings that form a hollow cylindrical shape and a second wire bent into a second waveform and spirally wrapped into a second helix having a plurality of windings that form a hollow cylindrical shape. The first and second wires are disposed relative to each other such that the plurality of windings of the first wire and the plurality of windings of the second wire are disposed about a common longitudinal axis and the plurality of windings of the first wire and the plurality of windings of the second wire are axially offset from each other, with windings of the plurality of windings of the first wire alternating or interwoven between windings of the plurality of windings of the second wire along a length of the prosthesis.

L'invention concerne une prothèse, comprenant un premier fil courbé en une première forme d'onde et enroulé en spirale en une première hélice présentant une pluralité d'enroulements qui revêtent une forme cylindrique creuse, et un second fil courbé en une seconde forme d'onde et enroulé en spirale en une seconde hélice présentant une pluralité d'enroulements qui revêtent une forme cylindrique creuse. Les premier et second fils sont disposés l'un par rapport à l'autre, de sorte que la pluralité d'enroulements du premier fil et la pluralité d'enroulements du second fil soient disposés autour d'un axe longitudinal commun, et que la pluralité d'enroulements du premier fil et la pluralité d'enroulements du second fil soient décalés axialement les uns par rapport aux autres, des enroulements de la pluralité d'enroulements du premier fil alternant ou étant entrelacés avec des enroulements de la pluralité d'enroulements du second fil le long d'une longueur de la prothèse.
