This invention relates to novel calcium phosphate coated implantable medical devices, and electrochemical deposition processes for making same. A process of coating an implantable medical device with a calcium phosphate coating comprising: (a) subjecting a substrate to a surface pretreatment whereby adhesion of the calcium phosphate coating to the substrate is enhanced; (b) immersing the pretreated substrate in an electrolyte comprising calcium and phosphate species; and (c) coating calcium phosphate onto the substrate by electrochemical deposition.
La présente invention concerne de nouveaux appareils médicaux implantables enduits de phosphate de calcium et des processus de dépôt électrochimique pour les réaliser. Un processus pour enduire un appareil médical implantable d'une couche de phosphate de calcium consiste à : (a) soumettre un substrat à un prétraitement de surface par lequel l'adhésion de la couche de phosphate de calcium au substrat est augmentée; (b) immerger le substrat prétraité dans un électrolyte qui comprend des espèces chimiques de calcium et de phosphate; et (c) enduire le phosphate de calcium sur le substrat par dépôt électrochimique.
