  • Patent number: 8343160
    Abstract: A medical inserter tool is provided for introducing medical implants into a surgical site, preferably using minimally invasive techniques. The inserter tool can have a variety of configurations, but in general, the inserter tool should be effective to engage and manipulate the implant into two or more positions. In an exemplary embodiment, the tool includes an elongate shaft having proximal and distal ends and defining a longitudinal axis extending therebetween, and a pivoting element that is coupled to the distal end of the shaft and that is adapted to engage a spinal implant. In use, the pivoting element is movable between first and second positions to allow an implant to be introduced through a percutaneous access device in a lengthwise orientation, and to be manipulated subcutaneously to be positioned in a desired orientation.

  • Patent number: 8333770
    Abstract: The present application is directed to various spinal stabilization systems. The systems can include one or more guiding elements attached to screw members to assist in guiding rod implants and tools to desired locations within a patient. The guiding elements can include a plurality of wires, blades, or tabs. The guiding elements can be capable of criss-crossing or intersecting at or near an incision, such that only a single incision may be needed to perform a surgery. The guiding elements can also include telescoping features that allow the height of the guiding elements to be adjusted in use, thereby allowing multiple telescoping guiding elements to be used with the same incision.

  • Patent number: 8317801
    Abstract: The present invention describes a targeting system suitable for guiding a biocompatible device to a target area within the body (in vivo) and method of using the same. The system includes a targeting member that is attached to the biocompatible device and may optionally include a steering material. The system includes a passer element located at the distal end of a wand. The wand includes a trigger like member adjacent a hand grip. Actuation of the trigger like member will result in a pivotal movement of the passer element that positions the targeting member such that the connected biocompatible device is positionable relative to the target area.

  • Patent number: 8277453
    Abstract: Vertebral column manipulation systems include spinal derotation instrumentation to affect one or more derotation maneuvers on a scoliotic spine or on a spine having one or more displaced, misaligned or curved vertebral levels. Derotation instrumentation is attached to at least one vertebral body, with the instrumentation including at least two elongated extensions mounted to and extending proximally from the at least one vertebral body. A linking assembly extends between and links proximal ends of the extensions to one another. The linking assembly includes first and second mounting assemblies movably engaged to an elongate link member extending transversely to the extensions. Each of the mounting assemblies includes a movable joint for receiving the proximal end of a respective one of the extensions and a cam assembly for securing the mounting assembly in position relative to the link member and to fix the joint around the extension.

  • Patent number: 8262666
    Abstract: A spinal implant for stabilizing two adjacent vertebrae having a damaged disc therebetween is assembled in situ. An elongated tool is used to insert a flat U-shaped distractor in the disc space through a low profile incision with both legs of the U-shaped distractor contacting both end plates of the adjacent vertebrae. The tool is rotated 90 degrees rotating the distractor 90 degrees so that each leg of the distractor contacts one end plate of the adjacent vertebrae, respectively, to restore intervertebral space. An elliptical bone tray is slid along the tool to seat within the U-shaped distractor. The tool is removed and a retainer replaces it to lock the bone tray and the distractor together. A screw is used to lock the bone tray to the distraction device, the screw slides down the cannula which is the tool inserted over the rod that the distraction implant is attached to.

  • Patent number: 8246659
    Abstract: A system for implantation of a spinal stabilization system includes a vertebral anchor having a top portion. The top portion has a perimeter and a first engaging element. The first engaging element has a first longitudinal axis that is generally parallel to a second longitudinal axis of the top portion. The perimeter extends around the second longitudinal axis. The system also includes a driving tool that has a second engaging element that is configured to cooperate with the first engaging element to substantially restrict rotation of the driving tool relative to the top portion about the second longitudinal axis. The first engaging element is configured to slidably receive the second engaging element in a direction along the first longitudinal axis, and the second engaging element is configured to extend substantially within the perimeter of the top portion.

  • Patent number: 8226656
    Abstract: A spinal surgical system includes at least one extender mounted to an anchor engaged to the spinal column. The extender extends proximally away from the anchor to a proximal end outside the patient. The extender is configured to receive a connecting member from an approach that is generally parallel or along the longitudinal axis of the extender so that the connecting member can be positioned from the proximal end of the extender to the anchor at the distal end of the extender without requiring an additional incision or puncture to accommodate the connecting member insertion.

  • Patent number: 8147524
    Abstract: Instrumentation and methods for reduction of a spinal deformity, including a plurality of elongate alignment elements and first and second reduction elements engaged to the alignment elements. Each of the alignment elements extends generally along a longitudinal axis and includes a proximal portion adapted for coupling to a corresponding vertebra and a distal portion. The first reduction element extends along a first transverse axis and is engaged with the distal portions of the alignment elements to maintain the distal portions in general alignment along the first transverse axis. The second reduction element extends along a second transverse axis and is movably engaged with the alignment elements wherein the proximal portions are positioned in general alignment along the second transverse axis as the second reduction element is displaced in a proximal direction to thereby reduce the spinal deformity.

  • Patent number: 8114092
    Abstract: An inserter for implanting an intervertebral spacer into a spinal disc space is disclosed. The inserter comprises a jaw assembly connected to a shaft assembly that is connected to a handle assembly. The user operates the handle assembly to open and close the jaw assembly to thereby connect to and release from the intervertebral spacer. Furthermore, the handle assembly is operable to lock and unlock rotation of the jaw assembly while still connected thereto to permit angulation of the jaw assembly relative to the shaft assembly without losing hold of the intervertebral spacer.
