The present invention provides devices and methods for removal of obstructive matter from the patients that are located inside or outside of the patient's endovascular system using rotational energy. One or more therapeutic agents may be delivered to the treatment location to further facilitate the removal process

The invention provides a grading transmission type energy-consuming damper. The invention belongs to the field of vibration control of building structures. A built-in foamed aluminum extrusion energy-consuming plate is arranged in the middle of the grading transmission type energy-consuming damper, two sides of the middle of the foamed aluminum extrusion energy-consuming plate are symmetrically provided with extrusion energy-consuming rubber plates, the left and right sides of each extrusion energy-consuming rubber plate are symmetrically provided with tension energy-consuming steel plates, and a connecting plate is arranged on the side of each tension energy-consuming steel plate away from the corresponding extrusion energy-consuming rubber plate. The grading energy consumption and transmission type multiple energy consumption effects can be achieved during tension. The grading transmission type energy-consuming damper has large initial rigidity, large yielding area of steel, and goodenergy consumption effect, a reserved gap is rotated to make the damper have a certain rotational energy consumption effect, an energy-consuming rib and a built-in elliptical hole make the energy consumption of the damper more sufficient, a lead pin has a good energy consumption effect and is easy to replace, the damping and energy consumption effects and the energy consumption magnification canbe adjusted according to the actual situation of a building structure, and the seismic response of the building structure can be reduced.
