Abstract
stent com elementos expansíveis. um stent implantável e redilatável, que é estruturado em forma tubular de filetes (11,11',11'') alongados, formando uma parede de implante, sendo que os filetes são de tal maneira plasticamente deformáveis que o implante (10) no estado expandido continua permanentemente dilatado em direção radial transversalmente ao eixol longitudinal dos filetes, é caracterizado pelo fato de que ao menos um dos filetes (11) apresenta um elemento de dilatação (12,12'), que forma um segmento de filete dentro desse filete (11), em que o elemento de dilatação no estado contraído se estende parcialmente geometricamente transversalmente ao eixo longitudinal do filete, sendo que o curso do elemento de dilatação com relação a esse eixo longitudinal apresenta várias alterações de direção, e o material, espessura e largura de filete do elemento de dilatação são de tal maneira selecionados, que por introdução de força em direção radial do implante tubular o elemento de dilatação pode ser levado por estiramentol plástico a um estado permanentemente expandido, em que o segmento de filete formando o elemento de dilatação apresenta uma dilatação geométrica maior transversalmente ao eixo longitudinal e uma dilatação menor em direção do eixo longitudinal do que no estado contraído. com isso pode ser consideravelmente aumenta a capacidade de dilatação do stent.
