Abstract:
1. A device for cutting tissue, comprising: an elongate body having a distal and proximal ends and a longitudinal axis; a rotatable cutting element, the rotatable cutting element being coupled to a torque transmitting element which extends through the elongate body; and a movable cover having distal and proximal ends and a longitudinal axis, the proximal end of the movable cover being slidably connected to the distal end of the elongate body, the cover being movable from a stored position, in which the rotatable cutting element is covered by the cover, to a working position, in which at least part of the rotatable cutting element is exposed outside the cover, the proximal end of the cover being axially aligned with the distal end of the elongate body when the cover is in the stored position, the proximal end of the cover being axially offset in a radial direction from the distal end of the elongate body when the cover is in the working position, the longitudinal axis of the cover being axially aligned with the longitudinal axis of the elongate body when the cover is in the stored position, the longitudinal axis of the cover being axially offset in a radial direction from the longitudinal axis of the elongate body when the cover is in the working position.
