Methods and devices for improved bonding of devices to bone

The present invention is directed to improving bonding between orthopedic devices, particularly vertebral devices, and bone. The present invention provides various methods and devices employing mechanical and bio-fixation modalities for such attachment. As provided herein, the initial mechanical attachment of a device to bone is sufficiently stable to ensure that the implanted device is relatively immobile (or alternatively microscopic motion is promoted), facilitating bone and soft tissue in-growth and the eventual bio-fixation of the device.

Low power thermoelectric generator

A thermoelectric generator has a top plate disposed in spaced relation above a bottom plate. A series of foil segments are electrically and mechanically connected end-to-end to generate a foil assembly that is spirally wound and in thermal contact with the bottom and top plates. Each foil segment comprises a substrate having a series of spaced alternating n-type and p-type thermoelectric legs disposed in parallel arrangement on the front substrate surface. Each of the n-type and p-type legs is formed of a bismuth telluride-based thermoelectric material having a thickness of about 10-100 microns, a width of about 10-100 microns and a length of about 100-500 microns. The alternating n-type and p-type thermoelectric legs are electrically connected in series and thermally connected in parallel such that a temperature differential between the bottom and top plates results in the generation of power.
