Abstract: A percutaneous path is established into a selected bone, e.g., a vertebral body, having an interior volume occupied, at least in part, by cancellous bone. A first bone filling material is conveyed through the percutaneous path into a region of the cancellous bone. A second bone filling material is conveyed through the percutaneous path into the region. The second bone filling material is different than the first bone filling material.

Abstract: A flow path is established into cancellous bone within a vertebral body through a percutaneous path. A bone filling material is conveyed into the flow path in a volume and at a pressure that results in an enlargement of the flow path volume. The enlargement can create a cavity and/or move a fractured cortical plate of the vertebral body toward a desired anatomic position. The bone filling material can comprise, e.g., a bone cement.

Abstract: A percutaneous path is established into a vertebral body, having an interior volume occupied, at least in part, by cancellous bone. A first bone filling material is conveyed through the percutaneous path into a region of the cancellous bone. A second bone filling material is conveyed through the percutaneous path into the region. The first and second bone filling materials can, e.g., incrementally create then enlarge a compressed region of cancellous bone, or displace the fractured cortical bone in increments.

Abstract: A percutaneous path is created into a bone having an interior volume occupied, at least in part, by a cancellous bone, e.g., a vertebral body. An expandable mesh structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable mesh structure is expanded and the tool withdrawn, leaving the expandable mesh structure expanded inside the cancellous bone. Expansion of the expandable mesh structure within cancellous bone can, e.g., compact cancellous bone, and/or create a cavity in cancellous bone, and/or move fractured cortical bone.

Abstract: A percutaneous path is created into a bone having an interior volume occupied, at least in part, by a cancellous bone, e.g., a vertebral body. An expandable stent structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable stent structure is expanded and the tool withdrawn, leaving the expandable stent structure expanded inside the cancellous bone. Expansion of the expandable stent structure within cancellous bone can, e.g., compact cancellous bone, and/or create a cavity in cancellous bone, and/or move fractured cortical bone.

Abstract: A cavity creation device is introduced into a cancellous bone volume of a vertebral body through a percutaneous access path. The cavity creating device is manipulated to form a cavity in the cancellous bone volume. A volume of filling material is placed in the cavity by introducing a tube through the percutaneous access path and by conveying the filling material through a side dispensing port of the tube.

Abstract: A method for delivering material into bone deploys a cannula through soft tissue to establish a subcutaneous path into bone. The method deploys a cavity forming instrument through the cannula to form a cavity in cancellous bone. The method introduces a material into the cavity through the cannula, which includes the advancement of a tamping instrument through the cannula to urge material into the cavity.

Abstract: Cephalad and caudal vertebral facet joint prostheses and methods of use are provided. The cephalad prostheses are adapted and configured to be attached to a lamina portion of a vertebra without blocking a pedicle portion of the cephalad vertebra. In some embodiments, the prosthesis is attached with a non-invasive support member, such as a clamp. In other embodiments, a translaminar screw may be used for additional fixation.

Abstract: A balloon for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone) against the inner cortex of bones whether the bones are fractured or not. The balloon comprises an inflatable, non-expandable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon is prevented from applying excessive pressure to the outer cortical bone. The wall or walls of the balloon are such that proper inflation the balloon body is achieved to provide for optimum compression of all the bone marrow. The balloon is able to be folded so that it can be inserted quickly into a bone. The balloon can be made to have a suction catheter. It can also be coated with therapeutic substances.

Abstract: The native cancellous bone volume of a vertebral body is altered to comprise a region of cancellous bone that has been compressed to form a compressed bone region that peripherally defines a cavity and another region of substantially uncompressed cancellous bone occupying at least a portion of the remaining native cancellous bone volume. A bone filling material occupies the cavity.

Abstract: A method provides a void creation device including an expandable structure adapted to undergo expansion in the cancellous bone volume of a bone selected for treatment. The expandable structure has at least one dimension so that the expandable structure will assume a predetermined shape and size when substantially expanded that compacts only a first volume of the cancellous bone volume to form a void, leaving a second volume of the cancellous bone volume substantially uncompacted by the expandable structure. A filling material is placed within the void through the percutaneous access path.

Abstract: Systems for treating a bone, e.g. a vertebral body, having an interior volume occupied, at least in part, by cancellous bone provide a first tool, a second tool, and a third tool. The first tool establishes a percutaneous access path to bone. The second tool is sized and configured to be introduced through the percutaneous access path to form a void that occupies less than the interior volume. The third tool places within the void through the percutaneous access path a volume of filling material. Related methods for treating a bone, e.g. a vertebral body, having an interior volume occupied, at least in part, by cancellous bone provide establishing a percutaneous access path to bone. A tool is introduced through the percutaneous access path and manipulated to form a void that occupies less than the interior volume. A volume of filling material is then placed within the void through the percutaneous access path.
