In accordance with the invention, there are provided medical devices with incorporated shape memory systems that allow a polymeric medical device to be inserted in a first conformation or configuration and revert to a second conformation or configuration. In another aspect of the invention, there is provided a medical device, such as a ureteral stent that comprises an elongate member (10) having a proximal end portion and a distal end portion joined by a body portion. The elongated member has an initial outer diameter. The member is formulated of a physiologically acceptable polymer capable of hydrating and expanding.
La présente invention concerne des dispositifs médicaux intégrant des systèmes à mémoire de forme permettant l'introduction du dispositif médical polymère sous une première conformation ou configuration, le dispositif médical revenant ensuite à une seconde conformation ou configuration. Sous un autre aspect, l'invention concerne un dispositif médical, et notamment un drain tuteur urétéral constitué d'un élément allongé (10) défini par une extrémité proximale et une extrémité distale, ces extrémités étant jointes par un segment formant son corps. L'élément oblong possède un diamètre externe initial. L'élément se compose d'un polymère physiologiquement compatible, capable de s'hydrater et de s'élargir.
