摘要: Described herein are devices and methods for cutting tissue in a patient. In some embodiments, a bimanually controlled device may include a tissue modification region; at least two flexible elongate lengths of cable that extend substantially adjacent to each other proximally to distally; a plurality of rungs extending between the lengths of cable; and a pair of flexible elongate cutting members extending along the length of the tissue modification region of the device. Each elongate cutting member has a thickness cuts a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. The device may further include a substrate sized and configured to releasably hold the cutting members a distance from one another and a pair of couplers positioned toward an outer edge region of the substrate and configured to releasably secure a cutting member to the outer edge region of the substrate.

摘要: A method for removing at least part of a brain tumor may first involve contacting a forward-facing tissue cutter disposed at the distal end of a tissue removal device with the brain tumor. The tissue removal device may include a shaft having a diameter no greater than about 10 mm, and in some embodiments the tissue cutter does not extend laterally beyond the diameter of the shaft. The method may next involve cutting tissue from the brain tumor, using the tissue cutter. The method may then involve moving the cut tissue through a channel of the shaft in a direction from the distal end of the tissue removal device toward a proximal end of the device.

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.
