Abstract:
A spinal cord device comprises a body formed of a biocompatible, biodegradable matrix and includes a proximal cranial surface and a distal caudal surface for connection to two ends of an injured spinal cord after removal of an injured section. The body has two sets of through channels A, B, C, D, E and F with openings in the cranial surface and the caudal surface for connection of descending motor pathways from cranial white to caudal gray matter and ascending sensory pathways from caudal white to cranial gray matter of the two spinal cord ends. The device has a transversal diameter (D t ) within a range of from  9  to  13  mm, an anteroposterior diameter (D a ) and a length (L), and the ratio anteroposterior diameter/transverse diameter (RAPT) is in a range of from  0.5  to  1.0 . Kits employ a plurality of such devices.

Claim (Index 1):
A spinal cord device for bridging an injured human spinal cord and promoting axonal regeneration, the spinal cord device comprising a body formed of a biocompatible, biodegradable matrix, the body including a proximal, cranial surface adapted for implantation on a cranial end of an injured spinal cord and a distal, caudal surface adapted for implantation on a caudal end of an injured spinal cord, for connection to a cranial end and a caudal end, respectively, of an injured spinal cord after removal of an injured spinal cord section; the body having two sets of through channels A, B, C, D, E and F with openings in the cranial surface and the caudal surface for connection of descending motor pathways from cranial white to caudal gray matter and ascending sensory pathways from caudal white to cranial gray matter of the two spinal cord ends; the spinal cord device having a transversal diameter (D i ), an anteroposterior diameter (D a ) and a length (L);\n wherein D t  is within a range of from 9 to 13 mm and the ratio anteroposterior diameter/transverse diameter (RAPT) is in a range of from 0.5 to 1.0; wherein (a) the two sets of channels A-F are symmetrically arranged in each of the cranial surface and the caudal surface of the device at locations corresponding with anatomical positions in the cranial end and caudal end, respectively, of the removed spinal cord section, (b)(i) in the cranial surface:\n the channels A are positioned in opposite lateral funiculi and adjacent opposite posterior horns, \n the channels B are positioned in opposite anterior funiculi and adjacent the ends of opposite anterior horns, \n the channels C are positioned in gray matter at the ends of opposite posterior horns, \n the channels D are positioned in the posterior horns, between channels C and the lateral horns, \n the channels E are positioned in the posterior horns, between the channels D and the lateral horns, and \n the channels F are positioned in the anterior horns, between the channels B and the lateral horns, and \n (b)(ii) in the caudal surface:\n the channels A are positioned at the juncture of the respective anterior horn, posterior horn and the intermediate gray, \n the channels B are positioned in gray matter at the ends of opposite anterior horns and in opposite anterior funiculi adjacent the ends of the respective anterior horns, \n the channels C are positioned in opposite posterior funiculi and between the ends of opposite posterior horns, \n the channels D are positioned in opposite posterior funiculi and between the opposite channels C, \n the channels E are positioned in opposite posterior funiculi and between the openings for channels D and the intermediate gray matter, and \n the channels F are positioned in opposite lateral funiculi and adjacent the respective anterior funiculi, and \n (c)(i) channels A have a first diameter in a range of from 2.0-2.9 mm, and one or more of channels B, C, D, E and F have a second diameter in a range of from 1.1-1.6 mm, or (c)(ii) channels A have a first diameter in a range of from 2.0-2.9 mm, channels E have a second diameter in a range of from 1.1-1.6 mm, and channels B, C, D and F have a third diameter in a range of from 0.5-0.9 mm.
