Title
(EN) METHOD AND APPARATUS FOR MANUFACTURE OF COVERED STENTS
(FR) PROCÉDÉ ET APPAREIL DE FABRICATION DE STENTS RECOUVERTS
Abstract
(EN)
The present disclosure is directed to an apparatus (100) for applying a graft material to a stent. (4) The apparatus may include a hollow mandrel (3) adapted to receive a stent. The mandrel (3) may include apertures adapted to allow a vacuum to be applied in order to temporarily affix the graft material sheath (20) to the stent. A forming roller (8) lying axially parallel to and in contact with the stent (4) may be included. Rotation of the forming roller may rotate the stent about its longitudinal axis. A second roller (9) for applying the sheath (20) of graft material to the stent as the stent (4) is rotated about its axis may be included. Further, the present disclosure is directed to a method of manufacturing stent grafts.
(FR)
La présente invention concerne un appareil (100) destiné à appliquer un greffon à un stent (4). L'appareil peut comprendre un mandrin creux (3) prévu pour recevoir un stent. Le mandrin (3) peut comprendre des ouvertures prévues pour permettre d'appliquer un vide afin de fixer temporairement la gaine (20) de greffon au stent. L'appareil peut également comprendre un rouleau (8) de mise en forme en position axialement parallèle au stent (4) et en contact avec celui-ci. La rotation du rouleau de mise en forme peut faire tourner le stent autour de son axe longitudinal. L'appareil peut comprendre en outre un deuxième rouleau (9) servant à appliquer la gaine (20) de greffon au stent tandis que le stent (4) tourne autour de son axe. La présente invention concerne également un procédé de fabrication de greffons pour stents.
