摘要:
A percutaneous access path into a vertebral body is established. The vertebral body has an interior volume occupied, at least in part, by a cancellous bone. At least portion of the cancellous bone is compacted or otherwise conditioned, resulting in a cavity in the vertebral body. A bone filler material is conveyed into the cavity at a pressure less than approximately 400 pounds per square inch. The bone filler material can have a viscosity that resists extravazation in cancellous bone.
摘要:
A posterior percutaneous path is established into a bone having an interior volume occupied, at least in part, by a cancellous bone. An expandable structure is introduced into the cancellous bone by deployment of a tool through the posterior percutaneous path into the cancellous bone. The expandable structure is expanded by introducing a filler material into the structure within the cancellous bone. The tool is withdrawn through the posterior percutaneous access path, leaving the structure and filler material inside the cancellous bone.
摘要:
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.
摘要:
The present invention relates to devices and methods for treating fractured and/or diseased bone. More specifically, the present invention relates to devices and methods for repairing, reinforcing and/or treating fractured and/or diseased bone using various devices, including cavity-forming devices.
摘要:
Introduction of a bone filler material into at least a portion of the cancellous bone volume pressurizes the bone filler material and compresses the cancellous bone volume within the bone structure.
摘要:
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 balloon structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable balloon structure is expanded and the tool withdrawn, leaving the expandable balloon structure expanded inside the cancellous bone. Expansion of the expandable balloon structure within cancellous bone can, e.g., compact cancellous bone, and/or create a cavity in cancellous bone, and/or move fractured cortical bone.
摘要:
A percutaneous path is established into a selected 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 within cancellous bone.
摘要:
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.
