    摘要： Various embodiments of a tissue cutting device are described, such as a device with 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 flat portion at its distal end perpendicular to the central axis, the flat portion extending from an outer circumference of the first annular element to the central axis; 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 flat portion at its distal end perpendicular to the central axis, at least one of the first or second annular elements rotatable about the central axis, the rotation causing the first annular element and the second annular element to pass each other to shear tissue.

    摘要： Medical devices for shearing tissue into small pieces are provided. One exemplary device includes oppositely rotating first and second rotatable members, each located at least partially within a distal housing. The device also includes first and second circular axle portions, and first and second blades that are directly adjacent to one another and positioned to partially overlap such that tissue may be sheared between the first and second blades, between the first blade and the second axle portion and between the second blade and the first axle portion. The rotatable members are configured to engage tissue from a target tissue site with teeth of the first and second blades, rotate towards one another and inwardly to direct tissue from the target tissue site through a tissue engaging opening and into an interior portion of the distal housing. Methods of fabricating and using the above device are also disclosed.
