    摘要： A method of thermally treating tissue during a surgical procedure where a surgical access device, including a body member having walls with at least one conduit therein, is inserted into the patient. A chilled fluid is circulated through the at least one conduit such that the tissue that is located proximate the body member is cooled. Alternatively, the body member may be constructed from a highly thermally conductive material such that heat energy is transmitted through the body from the tissue located proximate the body member and into a heat sink. The surgical device may include a first or second blade portions constructed from an inner and an outer shell having walls. Ribs located on the inner shell sealingly coupled to the inner wall of the outer shell to create the at least one conduit within the walls of the blade portion.

    摘要： A vertebral column correction system for correcting a spinal deformity without fusing the joint segments is disclosed. The vertebral column correction system may have first and second vertebral anchors secured to first and second vertebrae. The vertebral column correction system may further comprise one or more intermediate vertebral anchors secured to vertebrae between the first and second vertebrae. A connection member may be disposed within a head portion of the vertebral anchors. At least a portion of the connection member may be a flexible member, such as a flexible cord, configured for tensioning between at least two vertebral anchors for providing a desired amount of tension to apply a correctional force to the spinal column. A spring member, or other tensioning member, may maintain the tension of the connection member.

    摘要： A system for installing a cross member between first and second anchor members within a patient's body generally includes first and second docking members configured to be removably coupled to the respective first and second anchor members. Each docking member has a first end with an opening, a second end, and a body extending between the first and second ends. The body includes an outer surface with an opening, and a bore extends from the opening on the first end of the body to the opening on the outer surface. The openings on the outer surface of each docking member are configured to be aligned so that the bore in the first docking member is able to direct a wire member into the bore in the second docking member. A method for minimally invasive surgery using the system is also disclosed.

    摘要： In various embodiments, a spinal stabilization system has a first and a second vertebral anchor each adapted to be coupled to one of a first and a second vertebrae. The system also includes a flexible connecting element coupled to each of the first and second vertebral anchors and extending between the vertebral anchors. The connecting element has a central member and a brace positioned about the central member and the central member is stiffer than the brace to provide the needed combination of support and stiffness to the construct while offering flexibility. These and other various embodiments of this invention offer an improvement over known systems by providing stabilization of the vertebral column while allowing for flexibility and axial dampening.

    摘要： An artificial disc includes a top vertebra-attachment portion and a lower spacer support connected to the top vertebra-attachment portion; a bottom vertebra-attachment portion and an upper spacer support connected to the bottom vertebra-attachment portion. The spacer supports are disposed between the vertebra-attachment portions, and the lower spacer support is disposed between the bottom vertebra-attachment portion and the upper spacer support. The disc further includes a first elastic spacer positioned between the spacer supports for compressively resisting tensile loading of the disc; and a second spacer disposed between the bottom vertebra-attachment portion and the lower spacer support or between the top vertebra-attachment portion and the upper spacer support for compressively resisting compressive loading of the disc.
