A device for removing an implanted object from a body vessel includes an actuator having an elongated sheath extending therefrom, the elongated sheath including a proximal portion and a distal portion. A tubular outer member has a proximal end attached to the distal portion of the elongated sheath, with a ramped surface at a distal end of the tubular outer member which constricts a diameter of a bore formed in the tubular outer member. A tubular inner member is located within the tubular outer member, the tubular inner member including a proximal end operably connected to the actuator and a distal end opposite the proximal end, the distal end of the tubular inner member including a plurality of resiliently flexible blades positioned to interact with the ramped surface of the tubular outer member such that the ramped surface is operable to deflect the resiliently flexible blades radially inwardly as the tubular inner member is advanced distally within the tubular outer member. |
