Claim Text:
1. A method of implanting a device between adjacent spinous processes comprising: creating an incision in a patient to be treated; dilating any interspinous ligaments in a position in which the device is to be placed in the patient; sizing a space between adjacent spinous processes; and inserting the device between the adjacent spinous processes in a first position, the device comprising: moving the device to the second position to expand the wing member such that a portion of the inner surface of the wing member is capable of contacting a lateral surface of at least one of the spinous processes to limit movement of the device with respect thereto, inserting a guide wire laterally through the skin and into an interspinous space; creating a working portal concentric to the guidewire by inserting a series of sequentially larger diameter tubes to dilate the tissue surrounding the guidewire; and once a dilating tube having a sufficiently large inner diameter to accommodate the device is positioned about the guidewire, withdrawing the smaller diameter tubes, leaving the guidewire and the outer tube.
