Title
(EN) SWELLABLE POLYMER HYBRID FIBRES FOR A SLEEVE OF AN INTRALUMINAL ENDOPROSTHESIS
(FR) FIBRES HYBRIDES POLYMÈRES GONFLABLES POUR UN MANCHON D'UNE ENDOPROTHÈSE INTRALUMINALE
Abstract
(EN)
The invention relates to an intraluminal endoprosthesis (1), in particular a stent, having a biodegradable metallic supporting structure (2) and a biodegradable sleeve (3) surrounding the supporting structure (2), which sleeve comprises fibres (30) which are applied to the outer side of the supporting structure (2) by means of electrospinning, wherein the fibres (30) each have a polymer core (31) and a hydrogel casing (32) connected thereto or polymer and hydrogel fibres.
(FR)
L'invention concerne une endoprothèse intraluminale (1), en particulier un stent, ayant une structure de support métallique biodégradable (2) et un manchon biodégradable (3) entourant la structure de support (2), ledit manchon comprenant des fibres (30) qui sont appliquées sur le côté extérieur de la structure de support (2) par électrofilage, les fibres (30) ayant chacune un noyau polymère (31) et un boîtier d'hydrogel (32) relié à celui-ci ou des fibres polymères et d'hydrogel.
