Abstract:
1. A nerve regeneration-inducing tube, comprising: a tubular body comprising a plurality of fiber bundles woven together, each of said plurality of fiber bundles including a first polymer which is biodegradable and bioabsorbable and a second polymer which has higher biodegradability and bioabsorbability than the first polymer, wherein collagen is coated on the outer surface of said tubular body, wherein said tubular body is formed by weaving together said plurality of fiber bundles each including said first and second polymers, wherein the fiber bundles are formed by bundling ultrafine fibers of the first polymer and ultrafine fibers of the second polymer, wherein the first polymer is a polylactic acid and the second polymer is a polyglycolic acid, and wherein the ultrafine fibers of the first polymer are present at a ratio of 2/98 to 70/30 relative to the ultrafine fibers of the second polymer.
