Patent application numberDescriptionPublished
20100069967Instruments and Methods For Holding A Bone Plate - An instrument for insertion and placement of dynamic spinal fixation plates is provided. In general, the instrument is a clip that holds the plate at its maximum extension for implantation.03-18-2010
20100152854Methods and Devices for Expanding A Spinal Canal Using Balloons - An in-situ formed laminoplasty implant comprising an expandable bag containing a flowable, hardenable composition, wherein the implant may be shaped to act as a laminoplasty strut and be rigidly connected to a prepared lamina space.06-17-2010
20100241165LAMINOPLASTY METHODS USING HINGE DEVICE - A vertebra implant is provided that includes an elongate body with a first end configured to mate the first end to a first location on a vertebra, and a second end having at least one fastener configured to mate the second end to a second location on a vertebra. The elongate body also includes a deformable portion extending between the first and second ends that has an unexpanded configuration in which the deformable portion is configured to allow a tool to cut bone extending between the first and second ends when the first and second ends are mated to first and second locations on a vertebra, and an expanded configuration in which the deformable portion is deformed to increase a distance between the first and second ends such that a gap is created in the cut bone. The deformable portion is configured to maintain the first and second ends at a fixed distance apart when the deformable portion is in the expanded configuration. A vertebral implant is also provided that includes an elongate member configured to extend into a vertebra and form a hinge therein using a breakage point located along a length of the elongate member.09-23-2010
20100241230LAMINOPLASTY METHODS AND DEVICES - A vertebral implant is provided that includes a distraction member having a first end configured to pivotally couple to a first cut portion of a vertebra and a second end configured to mate with a base member configured to couple to a second cut portion of the vertebra. The distraction member can move relative to the base member to create a force effective to adjust a distance between the first and second cut portions of the vertebra.09-23-2010
20110172719Locking Bone Screw and Spinal Plate System - A bone plate system including a bone plate and a bone screw with an integrated locking mechanism is disclosed. The bone screw includes an elongate member having a threaded shank and a bone screw head that is radially deformable. The integrated locking mechanism sits within the bone screw head and can rotate between a locked condition and an unlocked condition. When the bone screw head is seated within an aperture in the bone plate, rotating the integrated locking mechanism into the locked condition helps to prevent bone screw backout.07-14-2011
20110190827HYBRID SPINAL PLATES - Various spinal plating systems for use in treating spinal pathologies are provided. In certain exemplary embodiments, the spinal plating systems can be configured to allow a surgeon to select a bone screw construct having a particular range of motion for attaching a spinal plate to bone as needed based on the intended use. In one exemplary embodiment, the spinal plating system includes a first bone screw that is polyaxially movable relative to the spinal plate, and a second bone screw that has a range of motion that is substantially limited to a single plane.08-04-2011

20080243192Passive Screw Locking Mechanism - Methods and devices are provided for passively locking a bone screw within a bone plate. In particular, the methods and devices allow a bone screw to be locked within a thru-hole in a bone plate without requiring any additional locking steps. In an exemplary embodiment, an annular feature is provided in a thru-hole of a bone plate, or in a bushing that is disposed within a thru-hole of a bone plate, for engaging a bone screw. The annular feature can be configured such that it allows the bone screw to be inserted through the thru-hole at various insertion angles while still being effective to prevent back-out of the bone screw, thereby locking the screw to the plate.10-02-2008

20110295283SOFT TISSUE REPAIR PROSTHESIS, EXPANDABLE DEVICE, AND METHOD OF SOFT TISSUE REPAIR - A hernia repair device is provided which may include a soft tissue repair prosthesis and an expandable device configured to be removably connected with the soft tissue repair prosthesis. When expanded, the expandable device may be configured to position the soft tissue repair prosthesis adjacent a hernia defect. The soft tissue repair prosthesis may include at least one loop or slit configured to receive a portion of the expandable device. The prosthesis may include a tether to hoist, locate or position the soft tissue repair prosthesis. The expandable device may include indicia for positioning the prosthesis relative to the edge of the hernia defect.12-01-2011
