A disc replacement spinal interbody fusion device is provided having a central sleeve with oppositely left and right-hand threaded axial bores with different diameters. Circumferential threaded apertures are located on the sleeve and open into the sleeve bores. The device has two opposing plates which are oval-shaped and centrally, axially bored. Each plate has a perpendicular shaft with an axial bore which communicates with the shaft bore. The first shaft has external left-hand threads and the second shaft has external right-hand threads, each to mate with different bores of the sleeve. The outside diameter of the first shaft is smaller than the inside diameter of the second shaft, allowing the two shafts to axially engage. The spinal interbody fusion device operates like a turnbuckle, vertically expanding when the sleeve is rotated in one direction and retracting when the sleeve is rotated in the opposite direction. The assembled device defines an open channel axially. Once the fusion device is set at its proper height, set screws are threaded into circumferential apertures of the sleeve to compress against the shaft threads of each plate to maintain a fixed height. In situ, axial loading of the spinal column upon the fusion device creates a bending moment manifested by a flexing action of the plates to generate opposing axial directional forces which replicate the physiological function of shock absorption, load bearing and load transmission.

The lack of safe, reliable, automated and clinically acceptable blood sampling has been the main problem precluding the development of real-time systems for blood analysis and subsequent closed-loop physiological function control. While the analysis of a static blood sample in laboratory conditions has been rapidly advancing in reliability and blood volume reduction, non-invasive real-time blood analysis performed in vivo (while the blood is circulating in the body) has been elusive and unreliable. In this study we propose an innovative idea for semi-invasive blood sampling and analysis, which resembles the operation of a mosquito. At a miniature scale the proposed system does penetrate the skin to extract a static blood sample for further analysis, but the extent of this penetration, and the fact that it can be made painless, is particularly attractive for such applications as automated glucose analysis for closed-loop control of insulin infusion (artificial pancreas), continuous drug monitoring, or even periodic DNA analysis for security and identification purposes. These design aspects are described, and a specific implementation, applying MEMS (Micro Electro Mechanical Systems) technology, is suggested. The proposed microsystem is a matrix of individually controllable e-Mosquito™ cells, packaged in a disposable patch and attached to the skin, could be an avenue for real-time semi-invasive blood analysis and diagnostics.
