Implants and methods for bone treatment, preferably minimally invasive treatment, including repositioning of vertebrae may comprise insertion of a bobbin having a wire, string, thread or band, coiled around the bobbin. 24 or more and a circle equivalent diameter of 10 \u03bcm to 150 \u03bcm. Also described methods of making such devices. The at least two guide members of the cable guide assembly orientates the wiring andor cabling in a generally vertical direction with respect to a heat emitting device so as to minimize the surface area of the wiring andor cabling that is exposed to a heat emitting device, thereby minimizing heat buildup within an enclosure. 05% and 5% by weight of the plastic formulation. An alternate embodiment includes a third layer.
