A method of creating a porous carbon coating on a medical device by applying a precursor carbon material on the medical device and then pyrolysing the precursor carbon material by laser irradiation. The laser irradiation may be focused to carbonize only certain portions of the medical device and any uncarbonized areas can be removed by solvent washing. Also provided is a medical device having a carbonized coating created according to the method of the present invention.
L'invention concerne une méthode pour réaliser un enduit en carbone poreux sur un appareil médical en appliquant un matériau précurseur de carbone sur l'appareil médical et en pyrolysant ensuite le matériau précurseur de carbone par irradiation au laser. L'irradiation au laser peut être concentrée pour ne carboniser que certaines parties de l'appareil médical et toutes les régions non carbonisées peuvent être retirées par lavage au solvant. L'invention concerne aussi un appareil médical ayant un revêtement carbonisé créé selon la méthode de la présente invention.
