Two variations of the CNF conduit model. a 12 mm long conduit with a 0.7:1 nerve to conduit diameter ratio and b 15 mm long conduit with a 1:1 nerve to conduit diameter ratio (no radial gap). Note that the diameter, length and relative placement of the proximal and distal nerve stumps have remained constant; however, the ends of the nerves are not shown to show the conduit section more clearly
