Title
(EN) MEDICAL DEVICES COATED WITH DIAMOND-LIKE CARBON
(FR) DISPOSITIFS MEDICAUX A REVETEMENT A BASE DE CARBONE SOUS FORME DE DIAMANT AMORPHE
Abstract
(EN)
A medical device (110) that has a sliding or peeling surface (114, 118, 120, 126) coated with diamond-like carbon (DLC) coating. The coating reduces sliding or peeling resistance. The coated substrates (112, 116, 122, 128) may be polymeric. The coating may be applied from a cold plasma of a hydrocarbon gas such as acetylene. Plasmas may be generated to deposit the coating on interior surfaces, exterior surfaces, or both.
(FR)
L'invention concerne un dispositif médical présentant une surface de glissement ou pelable, à revêtement à base de carbone sous forme de diamant amorphe (CDA). Le revêtement réduit la résistance au glissement ou au pelage. Les substrats revêtus peuvent être polymères. Le revêtement peut être appliqué au moyen d'un plasma froid d'un gaz hydrocarburé tel que l'acétylène. Des plasmas peuvent être générés de manière à déposer le revêtement sur des surfaces intérieures, des surfaces extérieures, ou les deux.
