摘要:
An apparatus includes a guide shaft, an expansion member coupled to the guide shaft, and an actuator. The expansion member is configured to impart a force from within an interior of an implant to deform the implant. The actuator is coupled to the expansion member, the actuator is configured to move the expansion member from a first position to a second position.

A vertebral body having an interior volume occupied, at least in part, by cancellous bone is selected for treatment. A percutaneous path is established into the vertebral body. A tool is introduced through the percutaneous path that creates a cavity in the cancellous bone. A bone filling material is conveyed to substantially fill the cavity. The bone filling material is pressurized within the cavity to enlarge the cavity.

An expandable device includes an expanded configuration and an unexpanded configuration. The expandable device is sized and configured for introduction into the cancellous bone volume of the vertebral body through the percutaneous access path while in the unexpanded condition. The expandable device is also sized and configured for expansion while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration, to create a cavity. The expandable device includes material sized and configured for controlling the expansion so that the expandable device expands more in an inferior-to-superior direction than in a lateral direction, so that the cavity that is created occupies less than the cancellous bone volume.
摘要:
A cannula establishes a subcutaneous path into bone. A tamping instrument can be manipulated independent of the cannula to enable insertion of the tamping instrument into the cannula, advancement of the tamping terminus in the cannula to urge material residing in the cannula into bone, and withdrawal of the tamping terminus from the cannula. The tamping instrument includes at least one marking to visually gauge the advancement of a terminus of the tamping instrument relative to a distal end of the cannula.

A vertebral body is selected having an interior volume occupied, at least in part, by cancellous bone. A tool is manipulated to create a cavity in cancellous bone. A bone filling material is conveyed into the cavity. At least one additional cavity is created in cancellous bone.
摘要:
A vertebral body is selected for treatment. The vertebral body has a cortical wall enclosing a cancellous bone volume. The vertebral body has at least one cortical plate that is depressed due to fracture. At least one maximum dimension for the cancellous bone volume is ascertained. An expandable device is provided having an expanded configuration and an unexpanded configuration. The expandable device has a predefined dimension when substantially expanded that is less than the maximum dimension. The expandable device is introduced into the vertebral body through a percutaneous access path while in the unexpanded condition. The expandable device is expanded while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration to create a cavity that occupies less than the cancellous bone volume.

An expandable device is introduced into a cancellous bone volume of a vertebral body through a percutaneous access path. The expandable device is expanded while disposed within the cancellous bone volume to create a cavity. A filling material including a biomaterial is placed within the cavity.
摘要:
A cannula establishes a subcutaneous path into bone. The cannula includes at least one predetermined marking. A tamping instrument is advanced through the cannula to deliver material into the bone by grasping an enlarged handle portion formed on the tamping instrument. The advancement is visually gauged by observing at least one predetermined marking on the tamping instrument to determine a position of a terminus of the tamping instrument relative to a distal end of the cannula.
摘要:
A vertebral body is selected for treatment. The vertebral body has a cortical wall enclosing a cancellous bone volume. At least one maximum dimension for the cancellous bone volume is ascertained, and an expandable device is provided that has a predefined dimension when substantially expanded that is less than the maximum dimension. The expandable device is introduced into the vertebral body through a percutaneous access path while in an unexpanded condition. The expandable device is expanded while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration. An expansion barrier is provided in association with the expandable device that directs expansion of the expandable device in a desired direction to create a cavity in the cancellous bone volume.
