Abstract: A medical device for removing a material from a hollow anatomical structure is provided. The device may include a shaft member. The device may include an expandable centering element near the distal end of the device. The device may include a macerator element either attached to the shaft or independent and freely moveable from the shaft. Alternatively, the device may include a rotating wire attached to the macerator element. The device may include an aspiration lumen in for removal of material. The device may include a drive shaft attached to a motor and used to rotate the macerator element. The device may be used in combination with a distal occlusion element, which may be either a radially expandable filter or balloon member.
