Abstract

Las modalidades descritas incluyen un dispositivo (20, 21) que incluye un soporte (22), que a su vez incluye una superficie exterior (24), y que está configurado para su inserción en el cuerpo de un sujeto. Además, el dispositivo incluye múltiples átomos (26) de un radionúclido, que se desintegra por radiactividad para producir un radionúclid hijo que se acopla a la superficie exterior y una capa (28, 33) de un polímero, que es permeable al radionúclido hijo que cubre a los átomos. También se describen otras modalidades.
