Title (EN) MEDICAL DEVICES WITH NANOTEXTURED TITANIUM COATING
(FR) APPAREILS MÉDICAUX AVEC REVÊTEMENT EN TITANE NANOTEXTURÉ
Abstract:
(EN) A system for treating a vascular condition includes a catheter, a stent disposed on the catheter, the stent having a stent framework including a core, the core having an outer surface and a pure titanium layer deposited on the outer surface of the core and a nanotextured surface formed in the deposited pure titanium layer. A method of manufacturing a stent for treating a vascular condition includes depositing a uniformly dense and uniformly thick layer of pure titanium onto an outer surface of a stent framework core, placing stent framework into a running chamber having a cathode and electrolyte solution, connecting stent framework and cathode to a power source operably connected to the running chamber, applying a power source to the attached stent framework and cathode for a predetermined length of time and at a predetermined voltage and forming a nanotextured surface within the deposited titanium layer.
(FR) L'invention concerne un système destiné à traiter une pathologie vasculaire et comprenant un cathéter, un stent disposé sur le cathéter et comprenant une structure de stent comprenant un noyau comportant une surface extérieure et une couche de titane pur déposée sur la surface extérieure du noyau, et une surface nanotexturée formée dans la couche de titane pure déposée. Un procédé de fabrication d'un stent destiné à traiter une pathologie vasculaire comprend le dépôt d'une couche uniformément dense et uniformément épaisse de titane pur sur une surface extérieure d'un noyau de structure de stent, le positionnement de la structure de stent dans une chambre de travail comprenant une cathode et une solution électrolyte, le raccordement de la structure de stent et de la cathode à une source d'alimentation raccordée opérationnellement à la chambre de travail, l'application d'une source d'alimentation à la structure de stent raccordée et à la cathode pour une durée prédéterminée, et à une tension prédéterminée, et la formation d'une surface nanotexturée dans la couche de titane déposée.
