A method and a mould for manufacturing a nerve regeneration device specifically adapted to an individual injury in the spinal cord are proposed, which will allow axons in the damaged area to regenerate and restore function. The resulting device can be adapted to a specific wound in order to ascertain an exact and reproducible anatomical positioning of the channels. The mould comprises a base plate (25), a top plate (27) and a centre part (33), each of said base plate (25) and said top plate (27) having a number of holes corresponding to points in the injured spinal cord where nerves should be regenerated, and said centre part having a channel therethrough, arranged to receive a number of threads, each thread exiting the mould through one hole in the top plate (27) and a matching hole in the base plate (25).
