20090138015 | 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. | 05-28-2009 |

20130182829 | ALIGNMENT SYSTEMS - Alignment systems and associated methods of using such systems to help aim an x-ray source at an x-ray detector are described in this application. The alignment systems can contain an electromagnetic radiation transmitter (or receiver) that is associated with the x-ray detector and an electromagnetic radiation receiver (or transmitter) that is associated with the x-ray source. Electromagnetic radiation produced by the electromagnetic radiation transmitter can be detected by the receiver and used to align the x-ray source and the x-ray detector in the x-ray device. In some configurations, the electromagnetic radiation transmitter contains a radio-frequency (RF) antenna (or antenna array) that is attached in a fixed position relative to the x-ray detector and the electromagnetic radiation receiver also contains an RF antenna (or antenna array) that is in a fixed position relative to the x-ray detector. Other embodiments are described. | 07-18-2013 |
