Abstract: Various embodiments of a tissue cutting device and methods for using are described. In some variations devices include an elongate tube having a proximal end and a distal end and a central axis extending from the proximal end to the distal end; a first annular element at the distal end of the elongate tube, the first annular element having a cutting portion at its distal; and a second annular element at the distal end of the elongate tube and concentric with the first annular element, the second annular element having a cutting portion at its distal end, the first and second annular elements being rotatable relative to one another to cause the first annular element and the second annular element to pass each other to shear tissue.

Abstract: The present disclosure relates generally to the field of tissue removal and more particularly to methods and devices for use in medical applications involving selective tissue removal. One exemplary method includes the steps of providing a tissue cutting instrument capable of distinguishing between target tissue to be removed and non-target tissue, urging the instrument against the target tissue and the non-target tissue, and allowing the instrument to cut the target tissue while automatically avoiding cutting of non-target tissue. Various tools for carrying out this method are also described.

Abstract: A bendable medical device such as for removing tissue from a subject is provided with a distal housing, an outer support tube, an inner drive tube, a coupler and a commutator portion. The coupler and commutator portion serve to axially constrain a distal end of the inner drive tube during bending, and to supply fluid for lubricating, cooling and irrigating the distal end of the device.
