1. A device for removing an implanted object from a body vessel, the device comprising:
a handle;
a trigger movably coupled to the handle;
an elongated sheath extending from the handle, the elongated sheath comprising a proximal end, a distal end, and a lumen extending from the distal end toward the proximal end, wherein the lumen is configured to receive an implanted object, the elongated sheath further comprising a proximal portion and a distal portion;
a tubular outer member attached to the distal portion of the elongated sheath, wherein at least one portion of the tubular outer member has a non-uniform circumferential wall thickness that is thicker at a distal end of the tubular outer member than at a proximal end of the tubular outer member;
a tubular inner member located within the tubular outer member, the tubular inner member comprising a proximal end, a distal end and an exterior surface therebetween, the distal end comprising a cutting surface; and
an actuator disposed within the handle, the actuator comprising a linear slide coupled to the trigger, such that upon movement of the trigger relative to the handle, the tubular inner member rotates and the distal end of the tubular inner member moves axially and extends distally beyond the tubular outer member.
