  • Monitoring and recording implantable silicon active pressure transducer
    Patent number: 8578795
    Abstract: An implantable active pressure transducer including a pressure sensing element and associated sensor circuitry together enclosed within an innermost glass packaging. The pressure sensing element is anodically bonded to the innermost packaging substantially aligned with an opening defined therein.

  • Spinal fusion implant
    Patent number: 8579983
    Abstract: The present invention provides a device and methodology for use in spinal fusion surgeries. An implant is proved for forming a rigid structure between adjoining vertebrae in a patient. The implant is a cage defined by at least a first end, second end, first side, and second side surface, wherein first and second side surfaces extend substantially parallel to each other to span a space between adjoining vertebrae and first and second ends interconnect said first side surface and second side surface. The cage incorporates one or more flexible joints that allow the cage to be deformed for insertion into a patient. The ability to deform the cage allows a greater ease and flexibility in inserting and positioning the implant.

  • Sacroiliac joint fusion alignment guide
    Patent number: 8579912
    Abstract: A device and method for defining a trajectory for instruments in a sacroiliac joint fusion procedure employs a handle and two movable guidance arms that are separated by an adjustable distance. The first guidance arm has a substantially straight pronged distal end terminating in a first prong, a second prong and a space between the first prong and second prong defining a first point in a straight trajectory for inserting screws into a sacroiliac joint. The guidance arm forms a receiving bore on a distal end thereof to define a second point in the trajectory. The pronged distal end is inserted through a posterior incision in the patient into a cored-out sacroiliac joint, with the second guidance arm outside the body, and the orientation of the alignment guide is adjusted by pivoting the alignment guide about the pronged distal end to determine a suitable trajectory.

  • Highly-versatile variable-angle bone plate system
    Patent number: 8574268
    Abstract: A bone plate system for internal fixation of bone fractures includes a bone plate having a plurality of bone plate holes. The holes are constructed to receive either a non-locking, locking, or variable-angle locking bone screw. The holes have discrete columns of teeth or thread segments arranged around the inner surface of the hole for engaging threads on the heads of locking and variable-angle locking bone screws. Conventional locking bone screws engage the bone plate coaxially with the central axis of the bone plate hole. Variable-angle locking bone screws can engage the bone plate at a selectable angle within a range of selectable angles relative to the central axis of the bone plate hole. The head of the variable-angle locking screw is at least partially spherical, and the thread thereon has a profile that follows the arc-shaped radius of curvature of the spherical portion of the screwhead.
