Abstract

resumo patente de invenção: "processo e dispositivo para a determinação de uma característica superficial em stents e stents com característica superficial definida". a invenção refere-se a um processo e um dispositivo para a determinação de uma característica superficial de um stent para o implante em um lúmen de um corpo, no qual um comportamento de umedecimento de uma superfície do stent serve como medida para a característica superficial da superfície do stent. para determinar o comportamento de umedecimento determina-se um decurso de uma capacidade de umedecimento ao longo de um comprimento da superfície do stent, sendo que a capacidade de umedecimento adjacente entre a superfície do stent e uma superfície líquida é detectada ao longo do comprimento do stent.
