摘要：
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.
