Abstract

Se proporciona una prótesis vascular que tiene diversas propiedades requeridas de la misma y tiene una función reparadora que es similar a la de los vasos sanguíneos en un organismo vivo y se basa en la capacidad de curación espontánea de un cuerpo humano. La tasa de cobertura de la capa interna C (%) se define por la fórmula: C = [{(W1 x D1 + W2 x D2) x 25,4 - W1 x W2 x D1 x D2}/(25,4 x 25,4)] x 100, donde D1 es la densidad de la urdimbre (extremos/25,4 mm) de la capa externa, D2 es la densidad de la trama (máximos/25,4 mm) de la capa externa, W1 es la anchura aparente (mm) de un hilo de urdimbre de la capa externa y W2 es la anchura aparente (mm) de un hilo de trama de la capa externa. La tasa de cobertura de la capa interna C (%), que representa la cobertura de una capa interna formada por hilo de urdimbre 3 e hilo de trama 4 por la capa externa formada por hilo de urdimbre 1 e hilo de trama 2, es del 15 % = C = 75%.
