  • Patent number: 6980922
    Abstract: A computerized model simulates the human spinal cord and makes it possible to draw inferences about the probability of future injury or the likelihood that specific injuries occurred in the past. The spinal cord is modeled by a plurality of two-dimensional graphs formed of a large number of finite elements. The two-dimensional graphs are stacked in positions corresponding to the measured positions of the spinal cord at various vertebral levels of a patient. The stacked graphs yield a three-dimensional model, which may be compared with similar data taken from other patients. The model may include the simulation of stress, applied to all or part of the spinal cord, resulting in a perturbed three-dimensional model which may again be compared with similar data taken from patients having known injuries. The invention can therefore be used, among other things, to verify claims of spinal injury as a result of vehicular or sporting accidents.

  • Patent number: 6665555
    Abstract: A system for delivery of high dosage of radiation to a targeted spinal area is provided. This is accomplished by a system which provides for precise immobilization and positioning of the treated spinal area during dose planning and treatment via stereotactic radiosurgery. Advantages of the system include convenience to the patient, enhanced efficacy, and reduced risk of radiotoxicity to non-target tissues.

  • Patent number: 6066175
    Abstract: A fusion stabilization chamber stabilizes the spine following removal of one or more vertebrae, and facilitates bone growth. The chamber includes two hollow members, preferably having slightly trapezoidal cross-sections, which slide relative to each other in a telescoping manner. The hollow members preferably have walls made of a metal mesh. Barrel vaults attached to the hollow members form guides for screws which can attach the chamber to the vertebrae adjacent the corpectomy site. Because of its adjustability, the chamber can fit a wide variety of corpectomy sites. One can fill the chamber with bone material, which can eventually fuse to the adjacent bone. A pair of stabilizing plates prevents the surgeon from pushing the chamber too far towards the spinal cord. The chamber eliminates the need to maintain a large and costly inventory of screws, and neurosurgeons can learn to use it quickly and easily. In another embodiment, the device is formed in one non-telescoping piece.
