Abstract
A nerve regeneration-inducing tube is provided which is excellent in cell growth property, resistance to pressure, shape recovery property, and anti-kink property in a nerve regeneration-inducing tube where a collagen solution is applied on the outer surface of a tubular body woven with ultrafine fiber comprising biodegradable and bioabsorbable polymer while collagen is filled in the inner area of the tubular body. The nerve regeneration-inducing tube has a degradation speed which is adjusted so as to make it suitable for the connection of nerve gaps of more than 40 mm. The nerve regeneration-inducing tube includes collagen coated on the outer surface of a tubular body woven with fiber bundles where plural ultrafine fibers comprising a biodegradable and bioabsorbable polymer are bundled. The tubular body mostly comprises a first polymer which is biodegradable and bioabsorbable and a second polymer which has higher biodegradability and bioabsorbability than those of the first polymer.
