Interspinous process spacer diagnostic parallel balloon catheter and methods of use
First Claim
1. A spinal surgery method using a device having an elongate member, a first main expandable member connected to a distal portion of the elongate member, a second main expandable member disposed in the first expandable member, a distal expandable member connected to the distal portion of the elongate member adjacent to a distal end of the first main expandable member, and a proximal expandable member connected to the distal portion of the elongate member adjacent to a proximal end of the first main expandable member;
- the method comprising;
inserting the distal portion of the device into the patient;
expanding one of the distal expandable member or the proximal expandable member;
determining whether the distal portion of the device is properly located;
thereafter, deflating one of the distal expandable member or the proximal expandable member;
repositioning the distal portion of the device;
inflating the proximal expandable member and the distal expandable member;
inflating the second main expandable member with a first volume of fluid;
identifying whether the patient experiences pain relief while the second main expandable member is expanded with the first volume of fluid;
after the identifying step, collapsing the second main expandable member, the proximal expandable member and the distal expandable member and removing the device from the patient.

Abstract
An interspinous process spacer diagnostic parallel balloon catheter and method. The balloon catheter has a plurality of maim expandable members disposed one inside another, a distal expandable member and a proximal expandable member that all can be expanded from a collapsed configuration to an expanded configuration and than 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.
