POWERED TISSUE MODIFICATION DEVICES AND METHODS
First Claim
1. A method for modifying tissue in a spine, the method comprising,passing a distal portion of a tissue modification device into a spine;
- positioning at least one tissue modifying member of the tissue modification device adjacent target tissue;
urging the tissue modifying member against the target tissue by applying at least one of anchoring force or tensioning force to a guidewire coupled to a distal portion of the tissue modification device; and
transmitting power to at least one drive member coupled with the at least one tissue modifying member to move the tissue modifying member and thus modify the target tissue.

Abstract
A device for modifying tissue in a spine may include: a shah having a proximal portion and a distal portion, the distal portion having dimensions which allow h to be passed into an epidural space of the spine and between target and non-target tissues at least one distal force application member extending from the distal portion of the shall and configured to facilitate application of at least one of anchoring force and tensioning force to the shaft; at least one movable tissue modifying member coupled with the shaft at or near its distal portion; at least one drive member coupled with the at least one tissue modifying member to activate the at least one tissue modifying member; and at least one power transmission member coupled with the at least one drive member to deliver power to the at least one drive member.

13. A method for treating spinal stenosis by removing spinal tissue, the method comprising,
advancing a guidewire into a patient'"'"'s spine; -
advancing a flexible distal portion of a tissue modification device into the patient'"'"'s spine using the guidewire; urging the tissue modifying member against the target tissue by applying at least one of anchoring force or tensioning force to the guidewire outside the patient and to a proximal end of the tissue modification device; and transmitting power to at least one drive member coupled with the tissue modifying member to modify at least one of ligamentum flavum or bone tissue in the spine. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
