Beschreibung
Zusammenfassung:	The present invention provides hydrogel coated, implantable medical devices and 10 methods of coating hydrogels onto implantable medical devices. In one embodiment, a hydrogel coated medical device is formed by 12 physically treating a surface of the medical device, 14 chemically treating the surface, 16 applying a hydrogel precursor and then 18 crosslmking the hydrogel precursor to form a hydrogel coating on the surface of the medical device. The present invention may be particularly applicable for coating articulating surfaces on implantable medical devices such as artificial joints. La présente invention concerne des dispositifs médicaux implantables enduits d'hydrogel et (10) des méthodes d'application d'hydrogels sur de tels dispositifs. Dans un mode de réalisation, Le dispositif médical enduit d'hydrogel s'obtient par traitement physique (12) de la surface dudit dispositif, par traitement chimique (14) de cette même surface, par application (16) d'un précurseur d'hydrogel et par réticulation (18) de ce précurseur dans le but de former un revêtement d'hydrogel sur la surface de ce dispositif. La présente invention peut convenir particulièrement pour l'application d'hydrogel sur des surfaces d'articulation de dispositifs médicaux implantables tels que des articulations.
