Patent ID: 8317831

Claim:
An interspinous process spacer diagnostic balloon catheter, comprising: an elongate member; a main expandable member connected to a distal portion of the elongate member and configured for disposal between adjacent spinous processes, the main expandable member comprises a height equal to a distance between adjacent spinous processes and a width substantially equal to the width of a typical spinous process; a distal expandable member connected to a distal portion of the elongate member adjacent to a distal end of the main expandable member and configured for disposal on a distal side of adjacent spinous processes; a proximal expandable member connected to a distal portion of the elongate member adjacent to a proximal end of the main expandable member and configured for disposal adjacent spinous processes on an opposite side of the distal expandable member; and a plurality of lumens disposed in the elongate member in communication with one or more of the main expandable member, the distal expandable member and the proximal expandable member, wherein the proximal and distal expandable members each have a height that is greater than the distance between adjacent spinous processes and greater than the height of the main expandable member, wherein the distal expandable member and the proximal expandable member are configured to lock the diagnostic balloon catheter in place.
