The present invention provides a precursor for producing a tissue regenerating instrument that regenerates a tissue, including: a tube made of a biodegradable material provided with a lumen in a longitudinal direction; a rod made of a biodegradable material swellable with a softening solvent, fixed to an inner wall of the tube substantially parallel to the longitudinal direction of the tube; and an adhesive that fixes the rod to the inner wall of the tube, in which the rod in a non-swelled state has an occupied cross-sectional area perpendicular to the longitudinal direction that is smaller than a cross-sectional area of the lumen of the tube, and the occupied cross-sectional area perpendicular to the longitudinal direction of the rod in a saturated swelled state with the softening solvent is substantially the same as the cross-sectional area of the lumen of the tube.

Precursor of a tissue regenerating instrument provided with a swellable rod

The present invention provides a nerve regeneration-inducing tube in which nerve is inserted into a tubular structure and can be easily sutured and fixed without resort to any special instruments or operations, thereby allowing nerve cells to efficiently proliferate and grow in the correct direction. The nerve regeneration-inducing tube of the present invention includes: a tubular structure (A) made of a biodegradable material or a bioabsorbable material and provided inside with a matrix (B) having linear nerve-inducing channels and being made of a biodegradable material or a bioabsorbable material; and a definite space part provided at one end of the tubular structure (A).

This invention relates to an instrument for regenerating a living organism tissue or organ, characterized in that a support (A) formed from a biodegradable material or a bioabsorbable material includes a sponge-like fine matrix (B) formed from a biodegradable material or a bioabsorbable material and a linear guide channel (C) for a living organism tissue or organ.
