System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.

A kyphoplasty cannula includes a shaft extending between opposite first and second end surfaces. The shaft has an inner surface defining a lumen. The shaft has a first opening that extends through the first end surface and a second opening that extends through the second end surface. A scoop extends from the second end surface. The scoop has an arcuate inner surface that is continuous with the inner surface of the shaft an opposite outer surface. The scoop has a rib. Kits and methods of use are disclosed.

The invention relates to devices and methods for creating a curvilinear cavity within a vertebral body or other body structure. An example method of forming a void in bony structure includes accessing a bony structure with a cannula, inserting a distal end of a combined drill and reaming device through the cannula and into the bony structure, manipulating the distal end of the combined drill and reaming device to create a void in the bony structure, and removing the distal end of the combined drill and reaming device from the cannula.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a radial opening at or near the distal end of the trocar. The system includes a curveable cannula sized to be received in the central channel, the curveable cannula comprising a curveable distal end configured to be extended laterally outward from the radial opening in a curved path extending away from the trocar. The curveable cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

Methods and apparatus for treating bones, including, in one or more embodiments, methods and apparatus for treatment of vertebral fractures that include a containment assembly for cement containment and/or a balloon assembly for maintaining vertebral height. A containment assembly comprising a containment jacket adapted to be deployed inside bone; and a dividing wall that separates the interior of the containment jacket into a proximal region and a distal region, the dividing wall having an opening for providing access to the distal region from the proximal region.

A device is disclosed that includes a bone stent positioned within a bony access channel formed within a vertebra. The bony access channel may extends from an outer end of the vertebra through an endplate. The device includes an end cap attached to a proximal end portion of the bone stent and is configured to, post-operatively, open to allow a reintroduction of a material to a spinal intradiscal space or intervertebral disc and to seal access to the spinal intradiscal space or the intervertebral disc after the reintroduction of the material.

Methods and devices for harvesting cancellous bone are disclosed. The bone-harvesting device may include a cannula and a bone receptacle in communication with the cannula, wherein the cannula including a cutting surface positioned at or adjacent the distal end, the cutting surface being oriented at an angle, the angle being greater than 90 degrees relative to the longitudinal axis of the cannula, and the harvested bone is adapted to move from a position adjacent to the cutting surface through the cannula into the bone receptacle. The cutting surface of the cannula may be positioned at or adjacent the distal end, and positioned at least in part radially outward of the outer face of the cannula. The cannula may include a cutting surface positioned at or adjacent the distal end and an occluding geometry that partially occludes the distal end of the cannula adjacent the cutting surface. In addition, a suction port may be provided in communication with the bone receptacle.

A system for restoring height of a vertebral body with a balloon and stabilizing the vertebral body with bone cement. A delivery tube extends from a handle and may be formed from a flexible polymer and a radiopaque filler. The flexible polymer maintains a patent lumen along a curve so as to receive sequential introduction of the balloon and the bone cement to within the vertebral body at a location offset from a longitudinal axis. The radiopaque filler provides for at least a portion of the delivery tube being radiopaque under fluoroscopic visualization. The radiopaque filler may be barium, and the delivery tube may be constructed from coextruding the flexible polymer with the barium. Visual indicia on the handle may indicate a position of the delivery tube relative to another component of the system such as an access cannula. The visual indicia may indicate a direction of the curve.
