A bicycle electrical system diagnostic device is provided for a bicycle electrical system in which several electric devices are connected. Wavelengths are assigned to each optical path; and the performance of the trail is assessed based on regenerator placement data and wavelength assignment data. An impedance converter circuit can be placed at the input or output of the interconnect to match the characteristic impedance of the interconnect. With this configuration, an intracranial electrode 1 in which the electrode 3 is arranged on the sheet-shaped silicone structure 2 having the three-dimensional shape of the gyrus or sulcus surface, or the interhemispheric fissure or interlobar fissure surface can be produced. Zcyto10 is useful for promoting the healing of wounds and for stimulating the proliferation of platelets. The deformable material may be brought into releasably secure contact with the stent by shifting the stent toward the balloon, the balloon toward the stent, or both.
