Abstract: The subject disclosure are directed to systems, apparatuses, devices and methods for vertebral and spinal correction. In some embodiments, an expansible implant is provided which may be inserted between two vertebrae, for instance, for maintenance and/or restoration of the distance/space between vertebrae. The implant may include first and second opposed plates that are intended to move away from one another, and which engage portions of vertebrae via a recess provided for on a bearing surface of the plates. The implant may additionally include at least first and second opposed end members, where at least one of the end members includes an aperture configured for receiving at least a portion of a retaining element adapted for retaining the implant in an expanded configuration once the implant is expanded. Methods of treatment and methods of use of such implants for the alleviation of back pain (for example) are also provided herein.

Abstract: The invention concerns a spinal osteosynthesis system comprising an anchoring member (1), a linking member (2), a lock (4) and interposition means (3) adapted to be placed in mounted position between the lock and the linking member when the latter are received in the anchoring member and designed not to overlap the anchoring member in mounted position, the interposition means (3) having at least one ridge for providing a support on the linking member.

Abstract: The invention described herein provides a method and apparatus that allows direct digital to IF/RF conversion using pulse-shaping. The method facilitates obtaining a flat or near flat output spectrum after digital to analog conversion with a minimal loss in signal energy. As opposed to pulse-shortening, where the DAC output pulse and consequently the energy per sample are reduced to a fraction a<1 of the maximum, the pulse-shaping does not shorten the DAC pulse. For each sample, pulse-shaping first stores the energy delivered by DAC and then releases the stored energy to the output during a short period of time aT. This way little signal energy is lost even for very small values of a. With pulse-shaping, the duration aT of the output pulse contributes to the spectral flatness in a way similar to that pulse-shortening, but has the additional benefit that the shape of the output pulse contributes significantly to a flat spectrum.
