A device for removing an implanted object from a body vessel, the device comprising: an inner sheath assembly comprising an inner sheath and a cutting tip disposed at a distal end of the inner sheath assembly, the cutting tip comprising a cutting surface adapted to cut tissue coupled to the implanted object as the cutting tip rotates; a handle assembly comprising a housing, a trigger carried by the housing, and a cutting tip drive mechanism carried by the housing and coupled to the trigger and the inner sheath assembly, the trigger being actuatable to drive the cutting tip drive mechanism and thereby rotate the inner sheath and the cutting tip relative to the housing; an outer sheath assembly carried outside of the inner sheath assembly, the outer sheath assembly comprising an outer sheath and an outer shield disposed at a distal end of the outer sheath assembly, the outer shield comprising a distal opening, the outer sheath assembly being translatable relative to the inner sheath assembly from a first position to a second position and vice versa whereupon the outer sheath assembly being in the first position, the cutting surface of the cutting tip remains disposed within the outer shield during actuation, and whereupon the outer sheath assembly being in the second position, the cutting tip extends through the distal opening and the cutting surface is at least partially disposed outside of the outer shield during actuation of the cutting tip drive mechanism; and a shield drive mechanism coupled to the outer sheath assembly, the shield drive mechanism being actuatable to translate the outer sheath assembly relative to the inner sheath assembly from the first position to the second position and vice versa. an inner sheath assembly comprising an inner sheath and a cutting tip disposed at a distal end of the inner sheath assembly, the cutting tip comprising a cutting surface adapted to cut tissue coupled to the implanted object as the cutting tip rotates; a handle assembly comprising a housing, a trigger carried by the housing, and a cutting tip drive mechanism carried by the housing and coupled to the trigger and the inner sheath assembly, the trigger being actuatable to drive the cutting tip drive mechanism and thereby rotate the inner sheath and the cutting tip relative to the housing; an outer sheath assembly carried outside of the inner sheath assembly, the outer sheath assembly comprising an outer sheath and an outer shield disposed at a distal end of the outer sheath assembly, the outer shield comprising a distal opening, the outer sheath assembly being translatable relative to the inner sheath assembly from a first position to a second position and vice versa whereupon the outer sheath assembly being in the first position, the cutting surface of the cutting tip remains disposed within the outer shield during actuation, and whereupon the outer sheath assembly being in the second position, the cutting tip extends through the distal opening and the cutting surface is at least partially disposed outside of the outer shield during actuation of the cutting tip drive mechanism; and a shield drive mechanism coupled to the outer sheath assembly, the shield drive mechanism being actuatable to translate the outer sheath assembly relative to the inner sheath assembly from the first position to the second position and vice versa.
