Title (EN) A METHOD OF PRODUCING THROMBOSIS-RESISTANT SURFACES
(FR) METHODE DE PRODUCTION DE SURFACES PERMETTANT D"EVITER LA FORMATION DE THROMBUS
Abstract:
(EN) A method of treating surfaces of medical devices which are to be brought into contact with blood or blood plasma for the purpose of rendering the surfaces resistant to thrombosis. The surfaces are treated with a wetting solution of a salt of a metal capable of causing peptide hydrogen ionisation and of forming complex compounds with heparin, hirudin and other anticoagulant proteins than hirudin, as a rhodium salt or a palladium salt, prior to applying thereto a coating of heparin, hirudin or other anticoagulant proteins than hirudin.
(FR) Une methode de traitement de surfaces d"instruments a usage medical destines a etre en contact avec le sang ou le plasma sanguin dans le but de conferer aux surfaces un effet s"opposant a la formation de thrombus. Les surfaces sont traitees avec une solution de mouillage d"un sel d"un metal capable de provoquer une ionisation hydrogene peptide et de former des composes complexes avec l"heparine, l"hirudine et des proteines coagulantes autres que l"hirudine, tel qu"un sel de rhodium ou un sel de palladium, avant d"y appliquer une couche d"heparine, d"hirudine ou des proteines anticoagulantes autres que l"hirudine.
