    Abstract: Methods and devices are disclosed herein that generally involve applying thermal therapy to tissue (e.g., localized cooling or heating of tissue), and in particular applying thermal therapy to the spinal canal, tissue disposed within the spinal canal, and/or nerve roots extending from the spinal canal. In some embodiments, tissue can be cooled or heated by implanting or positioning a thermal device in proximity to the targeted tissue. A number of exemplary thermal devices are disclosed, including bone anchors, inserts for use with bone anchors, K-wires, bone anchor extensions or towers, cross-connectors, spinous process plates, spinal rods, pedicle markers, bone taps, drill bits, bone plugs, bone plates, clamps, interbody or disc implants, thermal pads, and tubing loops. The thermal device can be left in place following surgery to facilitate application of post-surgical thermal therapy. In some embodiments, the thermal device can be removed post-surgery in a minimally- or non-invasive manner.

The transverse connector includes a first coupling assembly proximate a first end, a second coupling assembly proximate a second end, a first fastener having external threading configured to threadably engage an internal threaded portion of a housing of the first vertebral anchor, and a second fastener having external threading configured to threadably engage an internal threaded portion of a housing of the second vertebral anchor. Each of the first and second fasteners includes a spherical upper surface, such as a spherically concave upper surface. A spherical surface of each of the first and second coupling assemblies mates with the spherical upper surface of the respective fastener to provide multi-axial rotation of the transverse connector relative to the housings to permit a desired orientation of the transverse connector.

  • Patent number: 8657855
    Abstract: A spinal implant has two pairs of mounting plates or “staples,” two rods, and a crosslink. Each mounting plate mounts to a lateral side of a spinous process. Each rod interconnects a pair of mounting plates. The crosslink is disposed through the interspinous space and interconnects the rods. The crosslink hinders movement of the rods away from each other. The rods have a flexural modulus less than the mounting plates. The rod flexibility allows a small amount of relative movement of the vertebrae, which may be helpful in promoting fusion.

  • Patent number: 8657826
    Abstract: Apparatus and devices for adding an additional spinal construct in a patient are disclosed. In one arrangement the additional spinal construct extends an existing spinal construct ipsilaterally with an inline rod connector in a minimally invasive or preferably, percutaneous procedure. In another arrangement, the ipsilateral extension of an existing spinal construct uses an offset rod connector for receiving an additional spinal rod that may be placed interiorly or exteriorly of the existing spinal construct.

  • Publication number: 20140031867
    Abstract: A fastener assembly for a spinal fixation system that is particularly useful in treatment of pediatric and small-statured patients includes a fastener, an attachment member, and a locking member. The fastener has a lower portion for contacting a bone and an upper portion integral with the lower portion. The upper portion has two open channels. Each channel is configured and dimensioned to receive a portion of a longitudinal or connecting member along its circumference. The attachment member is positionable on the fastener and at least partially covers the channel that receives the longitudinal or connecting member. The locking member is operatively associated with the upper portion of the fastener and secures the attachment member and the longitudinal or connecting member to the fastener.

  • Patent number: 8636740
    Abstract: A spinal stabilization system includes an implant and instrumentation for stabilizing the spine. In one embodiment, the system includes a plate having a side rail and a channel extending adjacent the side rail. A pedicle screw assembly is positioned in the channel in releasable engagement with the side rail. The pedicle screw assembly includes a polyaxial screw seated in a lower housing having a lower locking flange. An upper housing having an upper locking flange secures the plate to the lower housing. The side rail of the plate is releasably engaged between the upper locking flange and the lower locking flange. The upper and lower housings include on-board locking mechanisms for fixing components in the screw assembly. The screw assembly and plate are inserted and oriented by remote manipulation. Minimally invasive techniques for inserting the implant are performed with the instrumentation, and cause minimal disturbance to surrounding tissue.

  • Patent number: 8579941
    Abstract: Superior and/or inferior facets of one or more facet joints may be replaced by superior and/or inferior facet joint prostheses. In one embodiment, a kit of superior or inferior prostheses is provided, in which the prostheses have at least two dimensions that vary among members of the kit independently of each other. Each prosthesis may have a bone engaging surface having a surface that is polyaxially rotatable against a corresponding resection of a vertebra. Each prosthesis may also have an articulating surface shaped such that, after attachment to the spine, the replaced or partially replaced facet joints provide a larger medial-lateral range of motion when the spine is flexed than when the spine is extended. Crosslinks may be used to connect left and right prosthesis together in such a manner that they are stabilized in a position in which they are seated directly against the vertebra.

  • Patent number: 8574232
    Abstract: An external fixation connection rod that allows for rapid and gradual length adjustment. In some embodiments, the fixation connection rod includes an inner sleeve received within a telescopic rod to allow for rapid adjustment of an overall length of the fixation connection rod. In some embodiments, the fixation connection rod includes an adjustment mechanism to allow for gradual adjustment of the overall length of the fixation connection rod by lengthening or shortening a threaded elongated member within the inner sleeve, and the adjustment mechanism includes a first rotation member, a second rotation member, and a spring. Distal translation of the first rotation member relative to the second rotation member allows the adjustment mechanism to move from a first, locked position to a second, unlocked position, allowing the first rotation member and the second rotation member to rotate about the inner sleeve and the threaded elongated member during gradual adjustment.
