Abstract

"STENT POLIMéRICO E MéTODO DE FABRICAçãO". A presente invenção refere-se a um stent formado de material polimérico, útil para expansão de um lúmen e a liberação de um ou mais agentes terapêuticos in situ. O stent pode ter múltiplas camadas e pode alterar a forma em um estado de temperatura de transição, governado pelos materiais que formam as camadas. São também descritos os métodos de uso e de fabricação.
