Title (EN) A MEDICAL DEVICE HAVING A SURFACE COMPRISING GALLIUM OXIDE
(FR) DISPOSITIF MÉDICAL PRÉSENTANT UNE SURFACE COMPRENANT DE L'OXYDE DE GALLIUM
Abstract: front page image
(EN)A medical device intended for contact with living tissue comprises a substrate having a surface, which surface comprises a layer comprising gallium oxide. A layer comprising a gallium oxide has been shown to inhibit biofilm formation on the surface of the medical device, which may reduce the risk for infection e.g. around a dental implant. A method of producing the medical device comprises: a) providing a substrate having a surface; and applying a gallium compound onto said surface to form a layer, preferably using a thin film deposition technique.
(FR)L'invention concerne un dispositif médical destiné à entrer en contact avec un tissu vivant, comprenant un substrat présentant une surface, laquelle surface comprend une couche contenant de l'oxyde de gallium. Il a été démontré qu'une couche contenant un oxyde de gallium inhibe la formation de biofilm sur la surface du dispositif médical, ce qui réduit le risque d'infection par exemple autour d'un implant dentaire. Un procédé de production du dispositif médical comprend : a) la fourniture d'un substrat ayant une surface ; et l'application d'un composé de gallium sur ladite surface pour former une couche, de préférence à l'aide d'une technique de dépôt de film mince.
