An interspinous process spacer diagnostic balloon catheter and method. The balloon catheter has a main expandable member, a distal expandable member and a proximal expandable member that all can be expanded from a collapsed configuration to an expanded configuration and then collapsed again to a collapsed configuration. The device can be used to determine whether a particular patient is a candidate for implantation of an interspinous process spacer to treat the symptoms of lumbar spinal stenosis and the size of such a spacer if indicated.

Interspinous process spacer diagnostic balloon catheter and methods of use

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 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 within cancellous bone by conveying a material into the mesh structure. Expansion of the mesh structure can, e.g., compact cancellous bone, and/or form a cavity in cancellous bone, and/or move fractured cortical bone.

Methods and devices for treating fractured and/or diseased bone using a mesh structure

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.

Methods for treating a fractured and/or diseased and/or weakened bone

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.

Methods and devices for treating fractured and/or diseased bone using an expandable stent structure

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.

Methods for treating fractured and/or diseased bone by introduction of different bone filling materials

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.

Apparatus and methods for use of expandable members in surgical applications

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 structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable structure is expanded and the tool withdrawn, leaving the expandable structure expanded inside the cancellous bone. Expansion of the expandable structure within cancellous bone can, e.g., compact cancellous bone, and/or create a cavity in cancellous bone, and/or move fractured cortical bone.

Methods and devices for treating fractured and/or diseased bone using an expandable structure that remains within the bone

An expandable body is inserted into an area of cancellous within a vertebral body through a percutaneous access path. A bone filler is conveyed into the expandable body to expand the expandable body and displace cancellous bone and create a cavity occupied at least in part by the expandable body and the bone filler. The expandable body and the bone filler are left within the cavity to strengthen the vertebral body.

Methods and devices for treating bone after high velocity and/or trauma fracture

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.
