Tip for lead extraction device
First Claim
1. A tip for engagement with an elongated sheath member for extracting an implanted structure from an obstruction in a body vessel of a patient, said sheath member having a proximal end, a distal end, and a passageway for said implanted structure extending therethrough, said tip comprising:
- a tip body having a smaller diameter proximal end and a larger diameter distal end, said smaller diameter proximal end sized for engagement with an inner surface of said sheath member distal end, said tip body distal end including at least one element disposed along at least a portion of an outer surface thereof, said element configured for at least one of cutting and disrupting said implanted structure from said obstruction.

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.

19. A device for extracting an implanted structure from an obstruction in a body vessel of a patient, the device comprising:
-
an elongated sheath having a proximal end, a distal end, and a passageway extending therethrough sized for receiving said implanted structure, said sheath having a length such that at least a distal portion of said sheath is receivable in said body vessel, said passageway sized such that said implanted structure is receivable therein;
a drive member operationally engaged with said elongated sheath for driving at least one of rotational and axial movement of said sheath; and
a tip engaged with said sheath distal end, said tip including a disruptor element at a distal end thereof for disrupting the obstruction. - View Dependent Claims (20)
