    摘要: A device for modifying one or more tissues in a patient's spine may include: an elongate, at least partially flexible body having a proximal portion and a distal portion, wherein at least the distal portion has dimensions that allow it to be passed into an epidural space and between target and non-target tissues of the spine; at least one movable blade disposed along one side of the elongate body; at least one actuator coupled with the at least one blade and disposed at or near the proximal or distal portion of the body for moving the blade(s) to modify one or more target tissues, wherein the at least one actuator is configured to move the blade(s) without significantly translating the elongate body proximally or distally; and means at or near the proximal and distal portions of the elongate body for facilitating application of at least one of anchoring force and tensioning force to the body to urge the at least one blade against the target tissue.

    摘要: A device for cutting tissue in a human body may include an elongate, hollow shaft having a proximal portion and a distal portion, a bundle of flexible wires slidably disposed within at least a portion of the shaft and having a proximal end and a distal end, and an actuator coupled with the proximal portion of the shaft and the proximal end of the bundle of wires. The distal end of the bundle may be configured to facilitate cutting of tissue, and the wires of the bundle may be at least partially free to move, relative to one another, to allow a cross-sectional shape of the bundle to differ along a length from the proximal to the distal end. The actuator may be configured to move the wires back and forth through the hollow shaft to cause the distal ends of the wires to cut tissue.

    摘要: 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.
