20080269898 | Device and method for image-based device performance measurement - Devices and methods for providing in vivo performance measurements of an orthopedic implant involve an orthopedic implant having at least two radiopaque markers associated with a movable portion of the implant. The markers are positioned at known locations and in a first known and predetermined relationship to each other. The markers provide visible references upon application of a medical imaging technique to show the relative position of the markers according to a second, changed relationship to each other after implantation of the orthopedic implant. At least one measurement of performance of the implant can be determined from the first and second relationships of the markers. | 10-30-2008 |
20080275504 | Constructs for dynamic spinal stabilization - Devices and methods for spinal stabilization include first and second anchors engageable to respective ones of first and second vertebrae and a connector assembly engageable with the anchors to provide a desired stabilization effect. The connector assembly includes a pair of bumper assemblies extending between the bone anchors and a connecting element extending through the bumper assemblies and connecting the first and second bone anchors to one another. | 11-06-2008 |
20080281360 | Spinous process implants and methods - Devices and methods for replacing one or more spinous processes of a patient include a replacement body with a lamina portion positionable anteriorly toward the spinal canal along with a spinous process portion extending posteriorly from the lamina portion to replace a removed spinous process. Connecting elements extend from opposite sides of the body for connection to the vertebral body with anchors. | 11-13-2008 |
20080281361 | Posterior stabilization and spinous process systems and methods - Posterior spinal stabilization devices and methods include first and second elongate elements engageable along the spinal column and a spinous process replacement body positionable between the elongate elements. Connection mechanisms are provided to adjustably connect the spinous process replacement device to the elongate elements so that the spinous process replacement device can be moved to the desired location between the connecting elements and secured in the desired location. | 11-13-2008 |
20090240283 | IMPLANTS AND METHODS FOR INTER-SPINOUS PROCESS DYNAMIC STABILIZATION OF A SPINAL MOTION SEGMENT - An implant assembly for stabilizing a spinal motion segment includes a spacer which is at least partially flexible and positionable between adjacent spinous processes. The spacer member includes upper and lower surfaces structured to receive a respective adjacent one of the upper and lower spinous processes of the spinal motion segment and a body having flexibly distinctive first and second sections relative to one another configured to modify the manner of movement at the spinal motion segment. | 09-24-2009 |
20100114320 | SURGICAL SPACER WITH SHAPE CONTROL - A surgical spacer comprising first and second hollow support members, a flexible container, and a compressible material disposed in the container is disclosed. The first and second support members each have an exterior and an interior cavity. The exteriors of the first and second support members are affixed together and the interior cavities of the first and second support members are connected via a connecting opening. The container is disposed in the interior cavities and extends through the connecting opening. In addition, the container is substantially impermeable to the compressible material. The first and second support members are more rigid than the flexible container. A combination of the first and second support members controls the shape of the flexible container, with the compressible material disposed therein, in response to a compressive load applied to an exterior of the spacer. | 05-06-2010 |
20100198265 | System, Devices and method for augmenting existing fusion constructs - One technique of the present application includes: evaluating a patient having a previously implanted spinal construct and corresponding spinal fusion from an earlier procedure and determining a spinal segment adjacent to the spinal fusion is degenerating after completion of the earlier procedure. After this determination, the previously implanted spinal construct is augmented by attaching a flexible polymer elongated member to the spinal segment adjacent to the spinal fusion with a bone fastener and by coupling the flexible polymer elongated member to one or more elements of the previously implanted spinal construct. In one form, the elongated member is at least partially comprised of polyetheretherketone. | 08-05-2010 |
20110015748 | System, device and methods for replacing the intervertebral disc with a magnetic or electromagnetic prosthesis - One embodiment of the present application includes a spinal disk prosthesis with one end portion to form a load transmitting relationship with one vertebra of a patient's spine and another end portion to form a load transmitting relationship with another vertebra of the patient's spine. A tube connects the end portions together and a damping material is positioned inside the tube. The end portions each include a magnet to generate a corresponding magnetic field. These magnetic fields are oriented to provide a repulsive force between the end portions to provide a magnetic bearing. | 01-20-2011 |
20120065684 | Intervertebral Prosthetic Device For Spinal Stabilization and Method of Implanting Same - A prosthetic device for insertion between first and second vertebrae comprises a unitary body having posterior and anterior portions. The posterior portion includes first and second flanges and the anterior portion includes third and fourth flanges. The first and third flanges form a first groove and the second and fourth flanges form a second groove. The first and second grooves are configured to extend through the sagittal plane when the body is disposed between first and second vertebrae. | 03-15-2012 |
