  • LATERAL INSERTION SPINAL IMPLANT
    Publication number: 20140012380
    Abstract: The present disclosure relates to a spinal implant. The spinal implant may be used for lateral insertion into an intervertebral disc space. For example, the spinal implant may include a spacer body to which a plate is fixed. The intervertebral spacer body may include a pair of opposite sides having a pyramid-shaped teeth to fuse to bone. The plate defines at least one upper and lower borehole that each receives a screw. Each screw attaches the plate to a vertebral body between which the intervertebral spacer body is inserted. The boreholes may include locking threads that are adapted to lock the screws into place by engaging complementary locking threads of head of the screw.

  • Radiopaque super-elastic intravascular stent
    Patent number: 8623071
    Abstract: The intravascular stent is formed from a composite wire includes an inner core of radiopaque metal, a polymer layer coaxially disposed about the inner core, and an outer metal layer coaxially disposed about the polymer layer. The intermediary polymer layer acts as a barrier material between the inner core and the outer sheath, so that the inner core and outer sheath may be made of dissimilar metallic layers, and the intermediary polymer layer will prevent a galvanic reaction between the inner core and the peripheral metal layer. The intravascular stent has ends flared radially outwardly to prevent radially and longitudinally inward deformation of the ends of the stent when the stent is disposed in a desired location in a patient's vasculature.

  • Bone Cement System For Bone Augmentation
    Publication number: 20140005635
    Abstract: A bone cement is provided that includes a solid component and a liquid component. The solid component and liquid component are mixed together to form the bone cement. After completion of the solid and liquid component mixing, the bone cement has an initial viscosity effective for manual application or manual injection onto or into a targeted anatomical location, e.g., bone, and the cement has stable viscosity range that over both time and temperature is effective for uniformly filling the targeted anatomical location, for example an osteoporotic bone or a fractured vertebral body, with minimal to no leakage of the cement from the targeted anatomical location. Additionally, both the initial viscosity and the stable viscosity of the bone cement are within a range that renders the bone cement effective for injection with a manually operated syringe or multiple syringes.
