摘要:
The present invention features new methods, apparatuses and devices for fixing adjacent bone segments, segments of a bony structure and adjacent vertebrate of a spine. The methods, apparatuses and devices utilize a new apparatus for forming a channel in a surface of the bone or bony structure segments or adjacent vertebra or a channel submerged within the bone or bony structure segments or adjacent vertebra. In more particular embodiments such apparatuses and methods including forming an arcuate channel and which channel can receive therein a curved rod or implant member, which also preferably is arcuate, and avoids the associated problems with prior cage or straight rod and screw systems. Also featured are systems, apparatuses and methods for repairing, replacing or augmenting the nucleus and/or annulus of a disc.

Featured are methods for fixing adjacent vertebrate of a spine that utilize an implant member, which preferably is arcuate. Preferred methods of the invention for stabilizing adjacent vertebrae of the spine, include forming an aperture in each of the adjacent vertebrae and inserting an implant into the apertures formed in each of the adjacent vertebrae so that the implant extends between the adjacent vertebrae and through the intervertebral space. An alternative method for fixing adjacent vertebrae of a spine includes the step of forming a common channel in and between the adjacent vertebrae and inserting an implant in the channel so as to bridge between the adjacent vertebrae. Also featured are methods for stabilizing adjacent segments of a bone, fixation systems and fixation kits.

Disclosed are apparatuses and methods for delivering implants through a posterior aspect of a vertebral body such as a pedicle and placing the implant or performing a procedure into the anterior aspect of the vertebral body. A representative apparatus includes an outer cannula, and advancer tube and a drill assembly. It is envisioned that at least one of the outer cannula, the advancer tube or the drill assembly can be viewed in vivo using for example, a CT scan or fluoroscope. The present invention is also directed to an apparatus for forming an arcuate channel in bone material. The apparatus includes and advancer tube and a drill assembly.

A method results in a system configuration wherein positioning a plurality of spargers reduces noise levels caused by fluid passing through the plurality of spargers. The method includes providing the plurality of spargers, each sparger having a center line access and an outer diameter measurement. Each of the plurality of spargers is positioned in a manner such that a ratio of the distance between the center line access of each sparger to the outer diameter measurement of each sparger is greater than a pre-determined ratio value. A greater ratio results in a reduction of noise emitted.

The present invention relates to devices and methods for altering the tissue in and around an intervertebral disc through localized hypothermia therapy to restore function of the disc and reduce pain. Hypothermia therapy is defined as the reduction of tissue temperature to below that of the equilibrium temperature. Target therapeutic temperatures and times are varied according to the desired treatment effect. Intended effects of hypothermia of the intervertebral disc include cellular disruption leading to cell death and or structural and chemical denaturation within the anulus fibrosus, nucleus pulposus, or nerve fibers, temporary or permanent deadening of the nerves within or surrounding the disc, induction of a healing response, angiogenesis, or accelerated degeneration and/or drying of the nucleus pulposus and/or anulus fibrosus. Various effects can be achieved by reaching different temperatures for differing periods of time or by the proximity of the hypothermia therapy device to the treatment target. Accordingly, it is an object of one or more the embodiments of the invention to provide hypothermic therapy to selected locations within an intervertebral disc utilizing a flexible and guidable cryogenic device.

A skate for conveying components into a monocoque locomotive. Portions of a monocoque locomotive platform are not accessible through a roof hatch. To move a component onto such portions of the platform, a skate assembly having an integral clamp assembly is attached to a leg portion of the component, the component is lifted onto the platform through a roof hatch, and the component is rolled on the skate rollers to the desired position on the platform. A jacking device integral to the skate assembly is then used to lift the component for removal of the rollers and for holding the component at a desired height for attachment to the locomotive.
