摘要：
Described herein are elongate devices for modifying tissue having a plurality of flexibly connected and rungs or links, and methods of using them, including methods of using them to decompress stenotic spinal tissue. These devices may be included as part of a system for modifying tissue. In general, these devices include a plurality of blades positioned on for formed from) rungs that are flexibly connected and may be separated by one or more spacers. The rungs are typically wider than they are long (e.g., rectangular). The rungs may be arranged, ladder like, and may be connected by a flexible connector substrate or between two or more cables. Different sized rungs may be used, or rungs with different cutting properties. In some variations the tissue modification devices may have a non-linear axial shape, or may be converted from a first axial shape to a second axial shape.
