- 摘要：
PROBLEM TO BE SOLVED: To provide a revascularization material being implanted in a living body, having a structure similar to the blood vessel tissue and having superior elasticity and elastic recovery rate.
SOLUTION: This revascularization material comprises (i) concentric inner layer, intermediate layer and outer layer, and has a hollow cylindrical shape with the outside diameter of 0.5-50 mm and the thickness of 200-5,000 &mum, each layer is composed of aliphatic polyester fiber with a mean fiber diameter of 0.05-10 &mum, the aliphatic polyester constituting the inner layer includes polylactic acid (PLA) and copolymer (PLCA) composed of 50-90 mol% of lactic-acid-derived repeating unit and 10-50 mol% of caprolactone-derived repeating unit, and the contents of the former and the latter are 40-100 wt.% and 0-60 wt.% respectively.
