ABSTRACT:
A method is provided for removing an implanted cardiac lead having a lead body and at least one conductive electrode from a mammalian body. The method includes the steps of providing an indifferent electrode, establishing electrical contact between the indifferent electrode and the body, and providing a generator of electrical energy. The method further includes the steps of coupling the generator between the conductive electrode and the indifferent electrodes and causing the generator to apply electrical energy between the conductive electrode and the indifferent electrode. The energy has a magnitude sufficient to produce gas by electrolysis between the conductive electrode and fibrotic tissue grown around the electrode. Thereafter, the lead body is pulled in an anterior direction relative to the mammalian body to remove the cardiac lead from the mammalian body.
