Abstract: A method and device for attaching a curvilinear access device having a movable top and an expandable working portal to the spine, the attachment including a holding arm assembly, posterior tang, anterior tang and/or a portal fixation pin.

Abstract: A curvilinear spinal access device having an expandable working portal. The device includes a slide having a channel with an open top and a movable top sized to cover the open top of the channel forming an expandable working portal with a proximal end and a distal end. The movable top can be moved between a closed position and an open position, wherein in the closed position the movable top blocks direct visualization between the proximal end and the distal end of the expandable working portal and in the open position movement of the movable top results in direct visualization from the proximal end to the distal end of the expandable working portal.

Abstract: An interbody spacer is provided. The spacer includes a housing having a top portion, a bottom portion, and a plurality of side portions disposed between the top portion and the bottom portion, a midline portion configured to be disposed across at least one of the top portion and the bottom portion of the housing, an opening disposed between the top portion and the bottom portion, and a grooved channel disposed in at least one of the plurality of side portions. The top and bottom portions are configured to include a plurality of projections configured to protrude away from the top and bottom portions.

Abstract: A wall or ceiling mountable lighting device comprises a self-contained single or multiple LED light source for emitting warm yellow-white light corresponding to halogen or incandescent light and a control circuit controlled by a remote control unit to energize and deenergize the light source and control light intensity. A rechargeable battery power source mounted on the lighting device is connectable to apparatus for charging the battery without removing the battery from the device. The apparatus includes an elongated probe assembly releasably connectable to the lighting device to perform the recharging process. The lighting device is particularly adapted for ease of placement of a light source for decorative purposes and/or illuminating artifacts in locations which would require substantial structural modifications to install conventional lighting.
