ABSTRACT:
Heart lead removal apparatus for removing an implanted cardiac pacemaker lead from the wall of a heart through a blood vessel leading to the heart. The lead removal apparatus comprises an outer tube sized for insertion into the coiled structure passageway of the pacemaker lead; an anchoring projection positioned proximate the distal end of the outer tube; and a stylet positioned through the passageway of the outer tube for urging the anchoring projection between relaxed and hooked positions. In the hooked position, the projection extends outwardly from the outer tube and when also positioned in the coiled structure passageway, hooks into the coiled structure for facilitating removal of the lead from the heart. In the relaxed position, the anchoring projection is insertable into the coiled structure passageway. In other aspects of the lead removal apparatus, the expandable means of the apparatus includes a barb positioned about the distal end of the outer tube; a slotted sleeve positioned between the distal ends of the outer tube and an actuator rod; and an expandable pliable plastic sleeve positioned between the pliable tube and the actuator rod.
