A method for treating a surface of a medical implant to create nanostructures on the surface that results in increased in-vivo chondrocyte adhesion to the surface. Further, disclosed is a method to fabricate a drug delivery system. The drug delivery system includes a medical implant that has un-dergone a surface treatment process that results in the modifica-tion of the surface configuration and topography. The modified surface acts as a depot or reservoir for loaded biological mate-rial, biologic agents or pharmaceutical products. Additionally, a device for delivering pharmaceutical products or other bio-logical materials is disclosed. The device includes integrally attached nanostructures that retain or adsorb the loaded phar-maceutical products and/or biological materials. Further dis-closed is a medical implant that includes a surface configured to allow for and regulate protein adsorption. The surface of the medical implant has a layer of nanostructures rigidly attached with varying porosity and orientation that allow for surface pro-tein adsorption to be controlled.

L'invention porte sur un procédé pour traiter une surface d'un implant médical afin de créer des nanostructures sur la surface qui conduisent à une adhésion accrue des chondrocytes in vivo à la surface. De plus, l'invention porte sur un procédé pour fabriquer un système de libération de médicament. Le système de libération de médicament comprend un implant médical ayant subi un traitement de surface qui a conduit à la modification de la configuration et de la topographie de la surface. La surface modifiée agit comme un dépôt ou un réservoir pour les matériaux biologiques, des agents biologiques ou des produits pharmaceutiques chargés. L'invention porte aussi sur un dispositif pour l'administration de produits pharmaceutiques ou de matériaux biologiques. Le dispositif comprend des nanostructures fixées d'un seul tenant, qui retiennent ou adsorbent les produits pharmaceutiques et/ou les matériaux biologiques chargés. L'invention concerne aussi un implant médical qui comprend une surface configurée pour permettre et réguler une adsorption de protéine. La surface de l'implant médical possède une couche de nanostructures fixées rigidement avec des porosités qui varient et une orientation qui permet le contrôle de l'adsorption de protéine à la surface.
