<p>An artificial neural tube the degradation rate of which in vivo can be controlled so that it can remain in vivo until the completion of the nerve regeneration and, after the nerve regeneration, which can induce the elongation along the proper direction of an axon regenerating from the end of the broken nerve without pressurizing the regenerating nerve and promotes the invasion of capillary blood cells so as to contribute to the early restoration of the blood flow, thereby promoting the regeneration of the nerve tissue, characterized by consisting of tubes (10, 20) having tubes (11, 21) made of a biodegradable/absorbable material and provided with coating layers (13, 23) on the external face thereof and collagen bundles [i.e., bundles of fibers (31) made of collagen], which have been dehydrated and cross-linked by heating, inserted into the tubes along the longitudinal axis and the collagen fibers being coated with laminin.</p> |
