Abstract
Disclosed is a heart lead removal apparatus (510) for removing a range of different sized implanted cardiac pacemaker or defibrillator leads (546) from the heart, typically through a blood vessel leading to the heart. The lead removal apparatus comprises a stylet (511), an expandable portion (513), and an actuator portion (512) which is manually advanced by the operator to cause the expandable portion to engage the coils (548) within a pacemaker coil lumen (551). In one preferred embodiment, the expandable portion comprises a multifilar wire bundle (515) that is helically wound around the stylet and attached about the tip (558) thereof. The actuator portion, which comprises an elongate metal cannula attached to a first handle (522), is urged forward to contact the proximal end (545) of the expandable portion, thereby causing the individual wires (514) of the multifilar wire bundle to deform outward in a random fashion.
