1. A method of removing an implanted lead from a vessel in the body of a patient, comprising:

  • providing a lead removal apparatus comprising an elongated proximal portion capable of having first and second configurations, the first configuration having a compacted, pre-formed shape being constrainable into the second configuration, the second configuration being sufficiently straight in shape to permit passage thereover by a sheath sized for insertion in said vessel and having a passageway extending therethrough, the first configuration having a diameter that exceeds a diameter of said sheath passageway and exceeds a diameter of said configuration;

    a distal portion including an expandable portion adapted to engage said implanted lead; and

    an actuator portion adapted to expand the expandable portion to effect engaging of said implanted lead;

    introducing the distal portion of said lead removal apparatus into the vessel;

    inserting the distal portion of said lead removal apparatus into said implanted lead;

    activating the actuator portion such that expandable portion expands and engages said implanted lead;

    grasping the elongated proximal portion; and

    applying traction to the proximal portion and retracting said implanted lead from said body.
