Title
(EN) STENT DELIVERY DEVICE
(FR) SYSTEME DE MISE EN PLACE D'UNE PROTHESE ENDOVASCULAIRE
Abstract
(EN)
A stent delivery device (20) is disclosed that includes an inner tube (30) having a distal portion (32) which carries the stent (10) on the delivery device (20). At least part of the inner tube (30) is formed from a spirally wound wire. A movable outer tube (50) is used to constrain the stent (10) in a radially contracted state on the distal portion (32) of the inner tube (30). A substantially straight elongate wire (34) is configured inside the spirally wound wire and bonded at the distal and proximal portions of the wound wire. The outer tube (50) may have at least one side port (54) adjacent to the distal portion in communication with the annular space between the outer tube (50) and the inner tube (30) allowing radiopaque fluid to be injected through the annular space and out the side port (54) in the vicinity of the stent (10).
(FR)
Système de mise en place d'une prothèse endovasculaire (20) comportant un tube intérieur (30) présentant une partie distale (32) conduisant la prothèse endovasculaire sur le système de mise en place. Une partie au moins du tube intérieur (30) est constituée d'un fil enroulé en spirale. Un tube extérieur mobile (50) sert à amener la prothèse endovasculaire à l'état rétracté sur la partie distale du tube intérieur (30). Un fil long sensiblement droit (34) est placé à l'intérieur du fil enroulé en spirale et fixé à ses extrémités proximales et distales. Le tube extérieur (50) peut comporter au moins un orifice latéral (54) touchant la partie distilale et communiquant avec l'espace annulaire compris entre le tube extérieur (50) et le tube intérieur (30) de manière à permettre l'injection d'un fluide opaque aux rayons dans l'espace annulaire jusqu'à l'orifice latéral d'où il parvient au voisinage de la prothèse endovasculaire.
