20090149958 | STRUCTURALLY REINFORCED SPINAL NUCLEUS IMPLANTS - A spinal nucleus implant is provided which includes a braided three-dimensional reinforcement member having a polymeric matrix imbued therein, the implant configured to have a shape consistent with a cavity within an intervertebral disc space. The polymeric matrix may be a fluid absorbing polymer, e.g., a hydrogel or a substantially non-fluid absorbing in-situ curable elastic polymer. A method of making a spinal nucleus implant is provided which includes providing a braided three-dimensional reinforcement member configured and dimensioned to have a shape consistent with a cavity in an intervertebral space and infusing the braided three-dimensional reinforcement member with a liquid polymer capable of forming a polymeric matrix. Also provided is a spinal nucleus implant including a three-dimensional reinforcement member adapted and configured to undergo anisotropic expansion, the implant configured to have a shape consistent with a cavity within an intervertebral disc space. A method of treating a degenerating intervertebral disc includes creating an incision in an annulus; removing at least a portion of a nucleus pulposus; and inserting, through the incision, a spinal nucleus implant according to the present disclosure. | 06-11-2009 |
20100100183 | SWELLABLE INTERSPINOUS STABILIZATION IMPLANT - A swellable, resilient interspinous implant is provided that includes a swellable polymeric medium, said polymeric medium being dispersed throughout the implant, the implant being dimensioned and configured to fit between two spinous processes of two adjacent vertebrae and buttress the space between the two adjacent vertebrae. In embodiments, the implant has a first configuration of reduced size such that it can be inserted into the patient in a minimally invasive manner. Once inserted to an application point within the patient, the implant expands in size to dynamically maintain the adjacent spinous processes in beneficial alignment. Also provided is a method of making a swellable, resilient interspinous implant as described herein. Also provided is a method of treating a degenerative condition of a spine which includes creating an incision and inserting, through the incision, between two spinous processes of two adjacent vertebrae, a swellable, resilient interspinous implant as described herein. | 04-22-2010 |
20100331987 | RADIALLY COMPRESSED DEHYDRATED SPINAL NUCLEUS IMPLANTS - A radially compressed xerogel spinal nucleus implant is manufactured and utilized for implantation into an intervertebral disc space. The implant has an optimized cross-sectional ellipsoid configuration which facilitates insertion of the implant through a minimal incision in the annulus. Radial compression is achieved by exerting substantially equilateral circumferential compression on an object contained within a radially collapsible member for exerting substantially equilateral circumferential compression on the object. Radial compression may also be achieved by exerting substantially equilateral circumferential compression force on a spinal nucleus implant via gas pressure in a sealed chamber. | 12-30-2010 |
20130282121 | SPINAL FACET AUGMENTATION IMPLANT AND METHOD - A spinal facet joint implant suitable for minimally invasive implantation and capable of transitioning from a compact first configuration to an expanded second configuration is made of a swellable and compressible fluid absorbing polymer. The implant is dimensioned and configured, while in the first configuration, to fit within the lumen of a surgical needle. In the expanded, second configuration, the implant exerts pressure within the facet joint which helps keep the facet joint from collapsing and anchors the implant in place. A spinal facet joint implant herein may also be dimensioned and configured to occupy a portion of the capsule of a facet joint. A spinal facet joint implant for treating inflammation made from a fluid absorbing polymer absorbs and sequesters inflammatory agents as it absorbs synovial fluid in situ. Methods of making and implanting a spinal facet implant are provided. | 10-24-2013 |

20130097507 | FILMSTRIP INTERFACE FOR SEARCHING VIDEO - An interface for searching and playing recorded video comprises a filmstrip snapshot sequence, a selection window, a first input device, a second input device, and a third input device. The filmstrip snapshot sequence comprises chronologically ordered snapshots associated with video segments of the recorded video. The snapshots are taken at regular intervals that may be equal to the length of the video segments. The selection window highlights consecutive snapshots from the filmstrip snapshot sequence. The first input device advances the filmstrip snapshot sequence, causing the selection window to highlight a chronologically later set of snapshots. The second input device zooms in on the filmstrip snapshot sequence as a function of time, causing a new set of snapshots to be retrieved at a smaller regular interval. The third input device causes the video segments associated with the highlighted snapshots to be played. | 04-18-2013 |
20130124997 | Digital video system with intelligent video selection timeline - A digital video system comprises a plurality of recorders and a client device. The recorders store digital video from a common source. The client device comprises a screen, an input device, and a processor configured to run a graphical user interface (GUI). The GUI comprises a timeline, a selection indicator, availability indicators, and event tags. The timeline is adjustable by user input. The selection indicator is movable on the timeline by user input, and designates a time of interest. The availability indicators indicate aggregate availability statuses of video at each time on the timeline, from the plurality of recorders. The event tags indicate types and times or time ranges of events on the timeline. The client device is configured to receive video availability information from the plurality of recorders, and the processor is configured to update the GUI as the aggregate availability status of video changes. | 05-16-2013 |
