Abstract: A tip for engagement with an elongated sheath member for use in extracting an implanted structure, such as a cardiac lead, from an obstruction in a body vessel of a patient. The tip includes a tip body having a smaller diameter proximal end and a larger diameter distal end. The smaller diameter proximal end of the tip is sized for engagement with an inner surface of the distal end of the sheath member. The larger diameter distal end of the tip includes at least one element disposed along at least a portion of the outer surface of the tip body distal end. The element has a shape configured for cutting and/or disrupting the lead from the obstruction.

Abstract: An extraction device for removing an implanted structure, such as a cardiac lead, from a body vessel. An elongated sheath having a proximal end, a distal end, and a passageway extending therethrough is sized such that at least a distal portion of the sheath is receivable in the body vessel. A tip configured for disassociating at least a portion of the implanted structure from the body vessel is engaged at the distal end of the sheath. A handle is configured for engagement with the proximal end of the sheath. The handle includes an actuator and a drive mechanism responsive to the actuator for selectively translating input of the actuator into rotary movement and/or axial advancement of the sheath.
