Abstract:
An apparatus includes an expandable member and an elongate assembly. The expandable member is configured to displace a first portion of a bone structure relative to a second portion of the bone structure when moved from a collapsed configuration to an expanded configuration. The elongate assembly includes a shaft and an elongated member disposed with a lumen defined by the shaft. A proximal end portion of the expandable member is coupled to a distal end portion of the shaft such that the proximal end portion of the expandable member does not rotate relative to the distal end portion of the shaft when at least a portion of the expandable member is twisted about the elongated member through at least four revolutions.
Abstract:
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.
Abstract:
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.
Abstract:
A method selects a vertebral body having an interior volume occupied, at least in part, by cancellous bone. The vertebral body has at least one cortical plate that is depressed due to fracture. The method establishes a percutaneous path into the vertebral body. The method introduces through the percutaneous path a tool that forms a region of compressed cancellous bone. The method conveys a bone filling material through the percutaneous path into the region to move the fractured cortical plate toward a desired anatomic position.
