Systems, apparatus, and methods for treating spinal tissue and other body structures in open and endoscopic spine surgery to relieve symptoms, such as neck or back pain. In particular, the present invention provides methods for the controlled heating of various tissues in or around the vertebral column, including various interspinous tissues, such that spinal ligaments and cartilage surrounding the vertebrae and the facet joints are shrunk or tightened to stabilize the vertebral column of a patient. Thermal energy is applied to the target tissue in a subablation mode of an electrosurgical system to cause shrinkage of the tissue, thereby stiffening the interspinous tissue and stabilizing the vertebral column. In an exemplary embodiment, a high frequency RF voltage can be applied between one or more active electrode(s) and one or more return electrode(s) to heat a target interspinous tissue to within a temperature range at which irreversible shrinkage of the tissue occurs.

An integrated system is described in which digital image data of a patient, obtained from a variety of image sources, including CT scanner, X-Ray, 2D or 3D scanners and color photographs, are combined into a common coordinate system to create a virtual three-dimensional patient model. Software tools are provided for manipulating the virtual patient model to simulation changes in position or orientation of craniofacial structures (e.g., jaw or teeth) and simulate their affect on the appearance of the patient. The simulation (which may be pure simulations or may be so-called “morphing” type simulations) enables a comprehensive approach to planning treatment for the patient. In one embodiment, the treatment may encompass orthodontic treatment. Similarly, surgical treatment plans can be created. Data is extracted from the virtual patient model or simulations thereof for purposes of manufacture of customized therapeutic devices for any component of the craniofacial structures, e.g., orthodontic appliances.

A small tabletop stationary five-degree of freedom device such as a “robot” is used to define the treatment region by tracing the region under direct visualization and then to precisely deliver the treatment plan created by an automatic planning system by positioning a single low energy radiation source, or a plurality of low energy sources connected to each other in a predetermined parallel or similar geometry, each source equipped with blocking and attenuation mechanisms, at a plurality of positions in a planar fashion across or through a selected treatment field, thereby delivering a plurality of parallel overlapping beams indexed on a millimeter or submillimeter grid such that a concentration of dose is achieved at a variable depth in tissue relative to the dose where the radiation first enters the tissue and can be used to treat regions on or below the surface of tissue, in a cavity and underlying region created following a surgical resection, on or below the surface of an internal cavity, hollow viscus, or lumen, or deep in tissue adjacent to an inserted probe or conduit or catheter. By generating a plurality of overlapping beams indexed on a millimeter or submillimeter grid that converge on a target volume loaded with gold nanoparticles, a tumorcidal dose of radiation can be delivered in as little as a single session to tumor cells but not to normal cells within or outside the treatment volume. This approach also makes it possible to deliver serial radiosurgical treatments.

Techniques for treating visceral or parietal membrane and tissue defects include the application of a collagen biomatrix to the defect to repair and regenerate a visceral or parietal membrane, for example in patients suffering tissue defects or undergoing visceral or parietal surgical treatment. Such approaches avoid persistent tissue leaks and their consequences such as fluid leaks and air leaks. The use of collagen biomatrix, optionally in conjunction with a fibrin sealant, an anti-adhesive, or both, can minimize tissue leaks or fluid leaks in injured patients suffering tissue defects or subjects undergoing surgery such as visceral or parietal resections and other operations.

Radiosurgical treatment of tissues of the heart to mitigate arrhythmias such as atrial fibrillation or the like. Radiosurgical targeting of the relatively rapid movement of heart tissues may be enhanced by generating a moving model volume using a time-sequence of three dimensional acquired tissue volumes. A digitally reconstructed radiograph (DRR) may be generated from the model at a desired cardiac and / or respiration motion phase and compared to an X-ray or the like taken immediately before or during treatment. When a series of radiation beams will be directed to a heart tissue to alleviate an arrhythmia, the treatment system may alter the radiation beam series in response to the type of the arrhythmia.
