According to an aspect of the present invention, implantable or insertable medical devices are provided, which contain one or more polymeric regions, which in turn contain at least one block copolymer. The block copolymer includes (a) at least one high Tg (glass transition temperature) polymer block that contains at least one high Tg vinyl ether monomer and (b) at least one low Tg polymer block that contains at least one low Tg vinyl ether monomer.
Selon un aspect, la présente invention concerne des dispositifs médicaux aptes à être implantés ou insérés, contenant une ou des zones à base de polymères, qui à leur tour contiennent au moins un copolymère bloc. Le copolymère bloc comporte (a) au moins un polymère bloc à température de transition vitreuse Tg élevée qui contient au moins un monomère de vinyle éthylique à température de transition vitreuse Tg élevée et (b) au moins un copolymère bloc à basse température de transition vitreuse Tg qui contient au moins un monomère de vinyle éthylique à basse température de transition vitreuse Tg.
