    摘要: A medical device such as for removing tissue from a subject is provided with a distal housing configured with a tissue cutter assembly, an elongate member coupled to the distal housing and having an outer tube and an inner drive tube with a crown gear located on a distal end thereof, first and second rotatable members each rotatably mounted to the tissue cutter assembly, a first drive gear train coupled between the crown gear and the first rotatable member, and a second drive gear train coupled between the crown gear and the second rotatable member. The first and second drive gear trains are configured to drive the first and second rotatable members, respectively, in opposite directions. Concave and convex gear tooth profiles are also disclosed for improved performance of the first and second drive gear trains.

    摘要: Described herein are elongate device for modifying tissue having a plurality of flexibly connected 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 (or formed from) rungs that are flexibly connected. The rungs are typically rigid, somewhat flat and 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. The blades (on the rungs) may be arranged in a staggered arrangement. A tissue-collection or tissue capture element (e.g., chamber, bag, or the like) may be used to collect the cut or modified tissue. 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.
