Abstract

L'invention concerne des compositions pouvant être radioactivées, de préférence des compositions d'alliages métalliques contenant un métal qui possède des caractéristiques de mémoire de forme, et au moins un isotope pouvant être radioactivé qui comporte un élément de la série des lanthanides ou des mélanges d'éléments de la série des lanthanides, ou un autre isotope approprié. L'isotope pouvant être radioactivé est présent selon une concentration suffisante (par rapport aux autres constituants de la composition) pour permettre l'administration d'une dose de rayonnement efficace à un tissu cible en vue d'atteindre un objectif thérapeutique spécifié. Une des applications les plus avantageuses et utiles de la composition est la formation de dispositifs médicaux utiles pour le traitement d'affections des artères coronaires et la réduction de la prolifération de cellules cancéreuses. Dans un des modes de réalisation préférés de l'invention, un isotope pouvant être radioactivé est incorporé, par une combinaison enrichie en isotopes, à une matière de matrice telle qu'un alliage de nickel/titane (p. ex. alliages de métaux du type nitinol), ou par une combinaison enrichie en isotopes à un polymère biodégradable organique naturel ou synthétique de manière à former une solution solide ; et l'alliage ou la solution solide obtenu(e) est ensuite façonné(e) en une endoprothèse ou en une autre forme appropriée pour l'administration sélective et ciblée de quantités thérapeutiques et efficaces de formes posologiques faibles de rayonnement (principalement de particules bêta) à un site ou à un tissu spécifique du corps humain.
