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