摘要： The present invention provides instrumentation that facilitates access to both sides of the vertebral body from a single access point. More particularly, the present invention provides bendable access devices that can be steered so as to traverse the vertebral body from the point of entry into the vertebral body, through the cancellous bone within the vertebral body, and to the contralateral side of the vertebral body. This steerability is provided by forming the access device with a series of slots, grooves, or notches in the side of the access device near the distal end of the access device, which slots, grooves, or notches reduce the bending stiffness of the access device. As a result, the distal end of the access device bends as it is being advanced into the vertebral body.

摘要： The invention relates to a method of creating a curvilinear cavity within a vertebral body or other body structure. The invention also relates to devices that may be used to perform the steps to create the curvilinear cavity. One such device is a curved drill including a lever and cam sub assembly. The curved drill can include a spring assembly that controls the curvature of the drill. The lever and cam sub assembly can be provided to allow tension to be reduced in the spring assembly.

摘要： A cement-directing structure for use in cement-injection bone therapy includes a collapsible, self-restoring braided structure with regions of differential permeability to the bone cement. The regions of differential permeability may be provided by areas where the braided mesh density is greater or lesser than surrounding areas and/or by means of a baffle. After the structure is placed in a void within a bony structure, cement is injected into the interior of the structure then oozes out in preferred directions according to the locations of the regions of differential permeability.
