Methods for treating a patient's spine
First Claim
1. A method for treating a subject, comprising:
- moving at least one dilator through an opening in the subject'"'"'s supraspinous ligament;
moving a cannula through the opening;
moving an implantable device through the cannula toward an interspinous space between adjacent vertebrae while the cannula extends through the opening in the supraspinous ligament; and
deploying the implantable device to distract and/or space apart the adjacent vertebrae, wherein the adjacent vertebrae include a first vertebra and a second vertebra, and wherein deploying the implantable device includesrotating a first cam lobe of the implantable device to position a first spinous process of the first vertebra between arms of the first cam lobe, androtating a second cam lobe of the implantable device to position a second spinous of the second vertebra process between arms of the second cam lobe.

Abstract
A plurality of individual tools is provided where each tool is uniquely configured to perform a step or a portion of a step in a novel procedure associated with the implantation of a stabilizing device (e.g., an interspinous spacer) for stabilizing at least one spinal motion segment. The tools are usable individually, or more preferably as a tooling system in which the tools are collectively employed to implant an interspinous spacer, generally in a minimally invasive manner. For example, each of the tools is arranged with coordinated markings and/or other features to ensure consistent depths of insertion, proper orientation of the tools with respect to each other or an anatomical feature of the patient, and precise delivery of the spacer to maintain safe positioning throughout the implantation procedure.

1. A method for treating a subject, comprising:
-
moving at least one dilator through an opening in the subject'"'"'s supraspinous ligament; moving a cannula through the opening; moving an implantable device through the cannula toward an interspinous space between adjacent vertebrae while the cannula extends through the opening in the supraspinous ligament; and deploying the implantable device to distract and/or space apart the adjacent vertebrae, wherein the adjacent vertebrae include a first vertebra and a second vertebra, and wherein deploying the implantable device includes rotating a first cam lobe of the implantable device to position a first spinous process of the first vertebra between arms of the first cam lobe, and rotating a second cam lobe of the implantable device to position a second spinous of the second vertebra process between arms of the second cam lobe. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A method for treating a subject, comprising:
-
moving a first dilator through an opening in the subject'"'"'s supraspinous ligament; moving a second dilator through the opening to dilate the opening in the supraspinous ligament; moving a cannula through the opening in the supraspinous ligament; moving an implantable device through the cannula while the cannula is positioned in the opening in the supraspinous ligament; and deploying the implantable device to distract and/or stabilize adjacent first and second vertebrae, wherein deploying the implantable device comprises; rotating a first cam lobe of the implantable device to position a first spinous process of the first vertebra between arms of the first cam lobe; and rotating a second cam lobe of the implantable device to position a second spinous process of the second vertebra process between arms of the second cam lobe. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method for treating a subject comprising:
-
moving one or more dilators through an opening in the subject'"'"'s supraspinous ligament; moving a cannula through the opening in the supraspinous ligament; moving an implantable device through the cannula that is positioned in the opening in the supraspinous ligament, the implantable device including a first cam lobe and a second cam lobe, the first cam lobe having first arms, the second cam lobe having second arms; and rotating the first and second cam lobes of the implantable device to position a first spinous process of a first vertebra between the first arms of the first cam lobe and to position a second spinous process of a second vertebra between arms of the second cam lobe. - View Dependent Claims (19, 20)
