Interspinous distraction devices and associated methods of insertion
First Claim
1. An interspinous distraction device for treating such conditions as lumbar spinal stenosis and degenerative disc disease, the interspinous distraction device comprising:
- a body assembly configured to be disposed between adjacent spinous processes of the spinal column of a patient, wherein the body assembly is sized such that the body assembly distracts the adjacent spinous processes apart; and
a plurality of attachment arms selectively extending outwardly from the body assembly in the direction of each of the adjacent spinous processes, the plurality of attachment arms configured to be disposed about a portion of each of the adjacent spinous processes and securely hold the body assembly in place relative to each of the adjacent spinous processes of the spinal column of the patient.

Abstract
In various exemplary embodiments, the present invention provides a plurality of novel interspinous distraction devices and associated methods of insertion. The interspinous distraction devices of the present invention are designed and configured to effectively treat such conditions as lumbar spinal stenosis and degenerative disc disease. Advantageously, the interspinous distraction devices of the present invention may be inserted through conventional open procedures, typically requiring a relatively large incision and a general anesthetic, or through novel minimally-invasive procedures, typically requiring only a local anesthetic. These novel minimally-invasive procedures and related enabling devices are also disclosed and described herein.
