A tip engageable with an elongated sheath member for extracting an implantedelongated structure, such as a cardiac lead, from an obstruction in a body vesselof a patient. The tip includes a tip body having a proximal end, a distal end, anda passageway extending therethrough. The tip body proximal end is engageablewith the distal end of the sheath member distal end. The passageway of the tip isaligned with the passageway of the sheath such that the implanted structure isreceivable therein. The tip body distal end includes a segment tapering towarda leading edge. A disruptor element, such as a plurality of helices, is disposedalong the outer surface of the tip body distal end. The disruptor element is configuredfor non-cuttingly disrupting the obstruction as the tip is advanced over theimplanted structure.
