BIO-COMPATIBLE AND BIOLOGICAL STABLE COATING OF MEDICAL SURFACES

摘要

This invention relates to medical products containing at least one biocompatible biologically stable polysulfone coating. The specified polysulfone coating makes it possible, by adding an adequate amount of at least one hydrophilic polymer, to regulate the kinetics of elution of at least one antiproliferative, anti-inflammatory, antiphlogistic and / or antithrombogenic agent that is introduced and / or applied with the possibility of spatial separation of different agents or different agent concentrations through a layered system of biologically stable polymers. Also described is a method of obtaining these medical products and their use, in particular in the form of stents, to prevent restenosis.
