CA 2272094

An artificial neural canal which remains in vivo until nerve regeneration, does not remain as a foreign substance in vivo after nerve regeneration, induces axon regeneration from nerve stumps, accelerates the penetration of capillaries from the organism, and thus accelerates the regeneration of nerve tissues. The neural canal comprises: tubes (10 and 20) comprising tubes (11 and 21) which are made of a material decomposable and absorbable in vivo and are covered on the inner and outer sides thereof with coating layers (12, 13, 22, and 23) made of gelatin or collagen; and collagen parts (30 and 40) disposed in the lumens of the tubes (10 and 20) and each having a space extending through the tube almost in parallel with the axis of the tube. Each space is filled with a matrix gel. A process for producing the artificial neural canal is also provided.

Canal rachidien artificiel qui reste in vivo jusqu'à la régénération nerveuse, qui ne reste pas un corps étranger in vivo après ladite régénération, qui induit la régénération des axones à partir de moignons de nerfs, qui accélère la pénétration des capillaires de l'organisme et qui accélère ainsi la régénération du tissu nerveux. Ledit canal rachidien comprend: des tubes (10 et 20) contenant les tubes (11 et 21) constitués d'un matériau pouvant se décomposer et être absorbé in vivo, et recouverts sur leurs côtés interne et externe des couches de revêtement (12, 13, 22 et 23) en gélatine ou collagène; et des parties en collagène (30 et 40) placées dans les lumières des tubes (10 et 20), et présentant un espace s'étendant dans le tube quasiment parallèlement à l'axe du tube. Chaque espace est rempli d'un gel matriciel. Un procédé de production dudit canal rachidien artificiel est également décrit.
