    摘要： Devices, kits, and methods are provided for treating a bone structure, e.g., a vertebra, with a compression fracture. Wedges can be introduced into the bone structure in a direction that is lateral to the compression fracture, and stacked on tope of each to apply forces to the bone structure to reduce the compression fracture. The wedges can be introduced into the bone structure using a cannula. The wedges can be introduced as wedge pairs, in which case, a subsequent wedge pair can be introduced between a previously introduced wedge pair in order to drive the previously introduced wedges apart to create the stacking arrangement. Optionally, the wedges can be provided with longitudinal bores, in which case, they can be introduced into the bone structure, over a guide member that is threaded through the bores.

    摘要： Devices and methods are provided for treating a bone structure (such as, e.g., reducing a bone fracture, e.g., a vertebral compression fracture, or stabilizing adjacent bone structure, e.g., vertebrae) is provided. The device comprises rigid or semi-rigid members, each of which comprises a common base and a plurality of ribs that extent along the a longitudinal portion of the common base. The device is configured to be placed in a collapsed state by engaging the pluralities of ribs of the members in an interposed arrangement, and configured to be placed in a deployed state by disengaging the pluralities of ribs. The ribs can be any shape, e.g., flutes, that allows opposing ribs to intermesh with one another. In this manner, the device has a relatively small profile when placed in the collapsed state, so that it can be introduced through small openings within the bone structure, while preserving the shear strength of the members during deployment of the device.

    摘要： A medical probe comprises a probe shaft having proximal and distal shaft portions, and an operative element, such as a tissue removal element, associated with the distal shaft portion. The proximal and distal shaft portions can be positioned relative to each other in an axially aligned relationship and an axially non-aligned relationship at the interface between the shaft portions. For example, the ends of the shaft portions that engage each other can be beveled, in which case, relative rotation of the shaft portions will cause the angle between the portions to vary. Or, the shaft portions can hinge relative to each other to vary the angle between them. Thus, it can be appreciated that the probe can be introduced along a straight path via a small opening within the patient, and then the probe shaft portions can be moved relative to each other to reach off-axis tissue. The probe may have a drive shaft that extends within the probe shaft and on which the operative element is mounted. The drive shaft may have proximal and distal rigid shaft portions and a linkage between the drive shaft portions, so that the drive shaft can bend when the probe shaft portions are placed in their axially non-aligned relationship.

    摘要： A probe and method for removing tissue is provided. The probe comprises an elongated member, a window laterally formed on the distal end of the member, a drive shaft rotatably disposed within the lumen of the member, and a rotatable tissue removal element disposed on the drive shaft. The tissue removal probe further comprises irrigation and aspiration lumens extending through the member in fluid communication with the window. In one method, target tissue, e.g., bone tissue, can be removed without removing non-target tissue, e.g., nerve tissue, by rotating the tissue removal element relative to the window. Fluid can be conveyed through the irrigation lumen into contact with the rotating tissue removal element. As a result of the rotation of the tissue removal element, the tissue is irrigated and removed, and forced towards the aspiration lumen. The irrigation fluid and removed tissue is then aspirated into the aspiration lumen.

    摘要： A tissue removal kit or assembly comprises a cannula and a tissue removal probe axially slidable within the cannula. The tissue removal probe comprises an elongated member a distal end configured to curve when distally deployed from the cannula. The tissue removal probe further comprises a drive shaft rotatably disposed within the member, and a rotatable tissue removal element (e.g., an abrasive burr) disposed on the drive shaft adjacent the member distal end. The curved member distal end may associate the tissue removal element, which has its own axis of rotation, with a radius of revolution about the longitudinal axis of the member. The member is laterally flexible and resilient, so that the radius of revolution can be adjusted. In this manner, the tissue removal element can remove tissue around an adjustable arc.
