Abstract
A method for manufacturing a nerve regeneration-inducing tube with excellent pressure resistance, shape recovery property, anti-kink property, film exfoliation resistance, resistance to invasion of outer tissues, and leakage resistance. The tubular body is formed by weaving together fibers made up of biodegradable polymer. The outer surface of the tubular body is coated multiple times with a collagen solution. The lumen of the tubular body is filled with collagen. Viscosity of the collagen solution that is first applied to the outer surface of the tubular body is between 2 to 800 cps. Viscosity of the collagen solution that is subsequently applied is higher than viscosity of the first applied collagen solution.
