Abstract
A method for modifying tissue in a patient may involve one or more of the following steps: advancing at least a distal portion of at least one elongate, at least partially flexible tissue modification device into a patient and between one or more target tissues and one or more non-target tissues; positioning at least one tissue modifying member of the tissue modification device adjacent the target tissue such that the tissue modifying member(s) face the target tissue and do not face the non-target tissue; applying an anchoring force to the tissue modification device at or near the distal portion or a proximal portion of the device; applying a tensioning force to the tissue modification device at or near an opposite end of the device relative to the end to which anchoring force is applied, while maintaining the anchoring force, to urge the tissue modifying member(s) against the target tissue; and modifying the target tissue, using the tissue modifying member(s), while preventing the tissue modifying member(s) from extending significantly beyond the target tissue toward the proximal or distal portion of the tissue modification device during tissue modification.
