Abstract: A fixation device includes a first anchor portion configured to join to a first bone portion, a second anchor portion configured to join to a second bone portion, and an intermediate component that extends between the first anchor portion and the second anchor portion. The intermediate component is configured to expand, contract, and angulate enabling constrained movement of the second bone portion with respect to the first bone portion. The second anchor portion has a larger configuration relative to the first anchor portion, thereby preventing the second bone portion from depressing below the first bone portion.

Abstract: Fixation devices and methods for stabilization of the lamina after laminoplasty are described. The device comprises of a plate with several holes that receive bone fasteners. The plate is curved at the ends to contour to the vertebral structure and has appendages to engage the displaced lamina in a fixed position. Alternatively, the plate has a bone fusion spacer in the middle to engage and fuse the lamina in the displaced position. Several methods of dynamically stabilizing the lamina after either the open door, double door or expansive laminoplasty technique are provided.

Abstract: The invention provides a method and apparatus for performing selective hypothermia to the brain and spinal cord for injury protection without the need for systemic cooling. A flexible catheter is inserted into the cerebral lateral ventricle or spinal subdural space. The catheter has lumens with a heat transfer element. The lumens of the catheter circulate a coolant and communicate at the distal heat transfer element for transfer of heat from the cerebrospinal fluid. Furthermore a method of maintaining catheter patency and providing blood clot hemolysis and drainage is also provided through the use of ultrasonic and/or laser energy delivered through the catheter.

Abstract: A method for treatment of a brain and/or spinal cord includes inserting a flexible catheter into a cerebrospinal fluid space, the flexible catheter including two lumens adapted to allow a fluid to circulate therein in a closed loop within the flexible catheter and the flexible catheter being adapted to be connected to a device for cooling and circulating the fluid. The cerebrospinal fluid in the cerebrospinal fluid space is cooled with the flexible catheter to enable selective central nervous system cooling. The functional status of the brain and/or spinal cord is monitored, and the treatment of the brain and/or spinal cord is modified to adjust for any change in the functional status of the brain and/or spinal cord.

Abstract: The invention relates to a method of central nervous system pathology treatment through selective hypothermia. Brain and spinal cord cooling is achieved through a closed loop catheter system inserted directly into the cerebrospinal fluid space. The catheter comprises of a portion that dilates in a pulsatile or peristaltic fashion and facilitates circulation of the cooled cerebrospinal fluid.
