Title
(EN) NANOPOROUS STENTS WITH ENHANCED CELLULAR ADHESION AND REDUCED NEOINTIMAL FORMATION
(FR) ENDOPROTHÈSES NANOPOREUSES PRÉSENTANT UNE ADHÉRENCE CELLULAIRE ACCRUE ET UNE FORMATION NÉOINTIMALE RÉDUITE
Abstract
(EN)
The present invention relates generally to medical devices containing nanoporous surfaces and methods for making same. More specifically, the invention relates to implantable vascular stents or other biomedical devices having at least one nanoporous layer that promotes improved cellular adhesion properties that promote healing and long term biocompatibility. In the case of stents, the nanoporous layer promotes re- endothelialization at sites of stent implantation vasculature, improves overall healing, and reduces inflammation and intimal disease progression. The nanoporous layer may be optionally loaded with one or more therapeutic agent to further improve the function of the implanted stent and further augment clinical efficacy.
(FR)
La présente invention concerne d'une manière générale des dispositifs médicaux contenant des surfaces nanoporeuses et leurs procédés de fabrication. Plus spécifiquement, l'invention concerne des endoprothèses vasculaires implantables ou d'autres dispositifs biomédicaux comportant au moins une couche nanoporeuse qui favorise les propriétés d'adhérence cellulaire propices à la cicatrisation et une biocompatibilité à long terme. Dans le cas des endoprothèses, la couche nanoporeuse favorise la reformation de l'endothélium au niveau de sites d'implantation d'une endoprothèse dans le système vasculaire, améliore la cicatrisation générale, et réduit l'inflammation et l'évolution d'une maladie intimale. La couche nanoporeuse peut éventuellement être dotée d'un ou de plusieurs agents thérapeutiques afin d'améliorer davantage le fonctionnement de l'endoprothèse implantée et d'en augmenter encore l'efficacité clinique.
