Abstract
In one embodiment, a stimulation lead for delivering electrical pulses from a pulse generator to tissue of a patient, comprises: a plurality of electrodes; a plurality of terminals; a plurality of conductors electrically coupling the plurality of electrodes with the plurality of terminals; a lead body of insulative material for enclosing the plurality of conductors; and at least one magnetic-field actuated switch for limiting MRI-induced current between the plurality of electrodes and the plurality of terminals, wherein the magnetic-field actuated switch is actuated by magnetostrictive material.
