Abstract
of WO 2009084572 (A1)
Provided is a nerve regeneration-inducing
tube comprising a tubular body which is obtained by knitting an ultrafine fiber
made of a biodegradable and absorbable polymer and has an outer surface coated
with a collagen solution and collagen packed in the interior of the tubular
body. The nerve regeneration-inducing tube is excellent in cell proliferation,
pressure resistance, shape restoration and kink resistance. In particular, a
nerve regeneration-inducing tube having a degradation rate adjusted so as to be
suitable for bridging a nerve gap exceeding 40 mm is provided. The invention is
directed to a nerve regeneration-inducing tube comprising a tubular body
obtained by knitting a fiber bundle formed of a plurality of ultrafine fibers
made of a biodegradable and absorbable polymer and having an outer surface
coated with collagen, characterized in that the tubular body is formed of
mainly a first polymer having biodegradability and absorbability and a second
polymer having higher biodegradability and absorbability than the first polymer.
