FIELD: medicine.
SUBSTANCE: invention relates to method of manufacturing medication-releasing medical device, selected from group consisting of vascular devices, prostheses, probes, catheters, tooth implants or similar, applied in treatment an/or prevention of vessel restenosis, which leads to acute circulatory collapse , conditioned by reduction of circulating blood weight. Claimed method includes application on device by means of submerging into suitable solution or by means of dispersion, of at least one medication layer, when necessary introduced into polymer able to release said medication; polymer which has active functional groups, selected from group consisting of amino groups and sulphhydryl groups capable of chemical binding of biological molecules in one step by means of cold plasma methods; and biological molecules on said polymer surface. Also described is medication-releasing medical device, obtained by said method and application of polymers with reactive functional groups for covering medical devices, preferably vessel stents, by means of cold plasma application.
EFFECT: due to application of definite class of polymers using cold plasma, claimed method is more technological, namely facilitates application of polymer without destroying its functional groups properties and better polymer binding with biomolecules resulting in slower, controlled release of medication from medical device.
