A device for extracting an elongated implanted structure from an obstruction within a vessel of a patient includes an inner sheath assembly and an outer sheath assembly. The inner sheath assembly includes an inner sheath and a tip, each having a passageway therethrough for receiving the implanted structure. The tip is configured for cutting and/or disrupting the implanted structure from the obstruction. The outer sheath assembly includes an outer sheath and a tip, each having a passageway therethrough for receiving the inner sheath assembly. The outer surface of this tip includes a plurality of raised elements circumferentially disposed therealong. The raised elements are configured for stabilizing the tissue of the vessel as the device is advanced through the vessel.
