Systems and methods for posterior dynamic stabilization of the spine

InactiveUS20080097441A1Reduces and eliminates facet painLiquidityInternal osteosythesisJoint implantsSpinal columnInterconnection
Systems and devices for dynamically stabilizing the spine are provided. The systems include a superior component for attachment to a superior vertebra of a spinal motion segment and an inferior component for attachment to an inferior vertebral of a spinal motion segment. The interconnection between the two components enables the spinal motion segment to move in a manner that mimics the natural motion of the spinal motion segment while substantially offloading the facet joints of the spine. Methods are also provided for stabilizing the spine and for implanting the subject systems.

Method and apparatus for path planning, selection, and visualization

New and Improved methods and apparatus for robotic path planning, selection, and visualization are described A path spline visually represents the current trajectory of the robot through a three dimensional space such as a room By altering a graphical representation of the trajectory—the path spline—an operator can visualize the path the robot will take, and is freed from real-time control of the robot Control of the robot is accomplished by periodically updating the path spline such that the newly updated spline represents the new desired path for the robot Also a sensor that may be located on the robot senses the presence of boundaries (obstacles) in the current environment and generates a path that circumnavigates the boundaries while still maintaining motion in the general direction selected by the operator The mathematical form of the path that circumnavigates the boundaries may be a spline

Bone anchoring system

Methods and apparatus for connecting to a bone, which avoid the use of bone screws. A triangular shaped modular implant is used, with two sides of the structure and their respective vertex secured generally within the bone, with the base of the triangle outside the bone. These two arms, whether straight or arcuate, are cannulated, and are held together at their distal ends by a tightened cable that runs through both of the arms. The proximal ends of these arms are connected to a base side that completes the triangular structure. The device may be inserted into a vertebra and the base used for vertebral fusion. Alternatively, the arms themselves may be used to stabilize and fixate adjacent vertebrae, by insertion through adjacent vertebrae trans-segmentally. In the latter case, the vertex may be within the intervertebral space or within the vertebral body close to the intervertebral space.

Spinal implants and methods

Spinal implants are disclosed that can be used for annular repair, facet unloading, disc height preservation, disc decompression, or for sealing a portal through which an intervertebral implant was placed. In some embodiments, an implant is placed within the intervertebral disc space, primarily within the region of the annulus fibrosus. In some embodiments, the implant is expandable. In some embodiments, the implant has a sealing tail structure comprising a tail flange and a linkage. In some embodiments, the sealing tail structure limits the extrusion or expulsion of disc material, either annulus fibrosus or nucleus, into the posterior region of the spine where it could impinge on nerves. In some embodiments, the tail structure is retained in place within the annulus fibrosus by means of an anchor. In some embodiments, the anchor is constructed from multiple components.

Dynamically amplified micromachined vibratory angle measuring gyroscopes, micromachined inertial sensors and method of operation for the same

A micromachined angle measuring gyroscope using a dual mass architecture measures angular positions rather than angular rates. The invention decouples the effects of drive and sense through the use of a dual mass architecture, and is comprised of a single lumped drive mass, which is structurally coupled to a second lumped slave mass, where the drive mass is electrostatically driven at the first resonant frequency the system using parallel plate electrodes. The slave mass is driven to higher amplitudes than the drive mass. In the presence of rotation, the line of oscillation in both masses precesses, which is easily detectable in the slave mass due to the amplified motion, and is exactly equal to the angle of rotation. The two illustrated embodiments are z-axis realizations of this principle, where the first device uses an inner drive / outer sense architecture and the second uses an outer drive / inner sense architecture.
