摘要：
It is an object of the present invention to provide a cylindrical body which has an excellent elastic modulus and elastic recovery and is suitable for use as a scaffold material for revascularization. It is a further object of the present invention to provide a cylindrical body which has an outermost layer with high air permeability, is excellent in cell infiltration and is suitable for use as a scaffold material for revascularization. The cylindrical body of the present invention is a hollow cylindrical body consisting of a plurality of concentric layers and having an outer diameter of 0.5 to 50 mm and a thickness of 200 to 5,000 μm, and each layer is made of aliphatic polyester fibers having an average fiber diameter of 0.05 to 50 μm.
