| 20120130436 | HEAD TO HEAD CONNECTOR FOR BONE FIXATION ASSEMBLIES - An apparatus and method for reinforcing a bone fixation assembly includes a first connector element for coupling to a first bone screw assembly, a second connector element for coupling to a second bone screw assembly, and an elongated connecting element that interconnects the first connector element and second connector element. An end of the first connector element is adapted to engage an elongated fixation element in a first bone screw assembly, and an end of the second connector element is adapted to engage an elongated fixation element in a second bone screw assembly. | 05-24-2012 |
| 20120095564 | KNEE PROSTHESIS - A knee prosthesis having a femoral component with two condyles, an opening disposed between the two condyles, and a tibial component having bearing surfaces to engage and support each of the femoral component condyles. Moving the femoral and tibial components in flexion from about 0° to about 165° causes medial pivot rotation of the femoral component upon the tibial component. Rotation may be caused by interaction between an asymmetrical cam extending between the femoral condyles and a post disposed between the bearing surfaces and extending superior from the tibial component. Rotation may alternatively be caused by asymmetrical medial and lateral condyles which translate posteriorly upon respective medial and lateral bearing surfaces at disparate rates, without a femoral cam, a tibial post, or a post/cam contact surface. Embodiments of the knee prosthesis may be used in cruciate-substituting or cruciate-retaining procedures. Embodiments of the knee prosthesis may also prevent roll forward. | 04-19-2012 |
| 20120022593 | SEMI-DYNAMIC FIXATION PLATE SYSTEM - A fixation plate system includes a plate with elongated slots, and first and second anchors for attaching the plate to vertebrae. The first and second anchors have different head configurations that are selected by the surgeon to control how settlement occurs at each fused segment. The head of the first fastener is insertable in any of the slots and resists translation. The head of the second fastener is insertable in any of the slots in free sliding engagement to allow translation of the head in that slot. In one method of use, the surgeon selects a segment where settling needs to be limited, and uses the first fastener to fix the plate near the segment and limit settling at that segment. The first and second fasteners have a built-in spring that assists in securing the fasteners in the plate. | 01-26-2012 |
| 20110313528 | STANDALONE INTERBODY FUSION DEVICE WITH LOCKING AND RELEASE MECHANISM - An implantable assembly includes an anchor member and a spacer. The anchor member has a hub portion and a shank portion. The spacer includes a central opening to receive bone fusion material and at least one passage for receiving the anchor member. In one embodiment, the passage includes first and second means for locking the anchor member in the passage against backout. The second means for locking the anchor member in the passage against backout includes means for centering the anchor member in the passage and means for stabilizing the anchor member in the passage. In addition, the second means for locking the anchor member in the passage against backout provides a mechanical advantage to assist in driving the screw into bone and mechanical advantage to assist in reversing the screw out of the spacer. | 12-22-2011 |
| 20110230916 | SCREW AND ROD FIXATION ASSEMBLY AND DEVICE - The present invention provides for a screw and rod fixation assembly for fixing a screw and, optionally, a rod. The screw and rod fixation assembly includes a screw, fixing mechanism, a substantially annular ring, rod seating mechanism, and locking mechanism. The present invention also provides for a fixing mechanism for fixing a screw, wherein the fixing mechanism further includes an inner surface wall having a gripping portion and a non-gripping portion. Further, the present invention provides for a substantially annular ring for guiding and providing mechanical and frictional force to a screw head. Additionally, the present invention provides for a rod seating mechanism operatively engaged to the screw head and including at least one flexible portion capable of being compressed against a portion of a rod therein. Finally, the present invention provides for a locking mechanism for engaging the rod and the rod seating mechanism. The locking mechanism includes a deflecting mechanism for deflecting the at least one flexible portion of the rod seating mechanism against and around the rod as the locking mechanism further engages the at least one flexible portion of the rod seating mechanism. | 09-22-2011 |
| 20110098715 | SELF-RETAINING SURGICAL DRIVER - A surgical tool includes a proximal end, a distal end and a longitudinal axis extending from the proximal end to the distal end. The surgical tool has a fastener engagement tip having a spring extension extending substantially parallel to the longitudinal axis of the surgical tool. The spring extension is resiliently flexible and deflectable between a first arrangement, in which the spring extension is in a relaxed state, and a second arrangement, in which the spring extension is deflected to facilitate insertion of the fastener engagement tip into a fastener slot. | 04-28-2011 |
