Abstract
A tip engageable with an elongated sheath member for extracting an implanted elongated structure, such as a cardiac lead, from an obstruction in a body vessel of a patient. The tip includes a tip body having a proximal end, a distal end, and a passageway extending therethrough. The tip body proximal end is engageable with the distal end of the sheath member distal end. The passageway of the tip is aligned with the passageway of the sheath such that the implanted structure is receivable therein. The tip body distal end includes a segment tapering toward a leading edge. A disrupter element, such as a plurality of helices, is disposed along the outer surface of the tip body distal end. The disruptor element is configured for non-cuttingly disrupting the obstruction as the tip is advanced over the implanted structure.
