Method and apparatus for modifying neurostimulation linear lead shape to correct lead migration

Abstract

A neurostimulation system comprises an implantable neurostimulation lead, an implantable neurostimulator configured for delivering stimulation energy to the implantable neurostimulation lead, an actuating device configured for modifying a linear shape of the lead after it has migrated from a baseline position, memory configured for storing a threshold value, and a processor configured for determining a magnitude at which the lead has migrated from the baseline position, comparing the determined magnitude to the threshold value, and prompting the actuating device to modify the linear shape of the lead based on the comparison. A method of correcting the migration of a neurostimulation lead implanted within the patient comprises determining a magnitude at which the implanted lead has migrated from a baseline position, comparing the determined magnitude to a threshold value, and modifying the linear shape of the lead based on the comparison.
