Title
(EN) POLYMER COMPOSITIONS FOR INTRALUMINAL STENT
(FR) COMPOSITIONS POLYMERES DESTINEES A UN STENT INTRALUMINAL
Abstract
(EN)
Polymer compositions for use in forming a stent are described. The compositions include a monomer of an aliphatic ester of acrylic acid which has a glass transition temperature less than 25 °C and a second monomer that copolymerizes with the first monomer and which has a glass transition temperature greater than 25 °C. The components in the compositions are mixed in amounts suitable to give a copolymer having a glass transition temperature less than 25 °C, or in case of block copolymers, having at least one glass transition temperature less than 25 °C. A stent including polymer members formed from the described compositions is also disclosed.
(FR)
La présente invention concerne des compositions destinées à la formation d'un stent. Les compositions de l'invention comprennent un monomère d'un ester aliphatique d'acide acrylique d'une température de transition vitreuse inférieure à 25 °C et un deuxième monomère capable de copolymérisation avec le premier monomère, d'une température de transition vitreuse supérieure à 25 °C. Les composants des compositions précitées sont mélangés dans des quantités permettant d'obtenir un copolymère d'une température de transition vitreuse inférieure à 25 °C ou, dans le cas de copolymères séquencés, présentant au moins une température de transition vitreuse inférieure à 25 °C. L'invention se rapporte également à un stent comprenant des éléments polymères formés à partir des compositions décrites ci-dessus.
