APPARATUS AND METHODS FOR DETECTING MIGRATION OF NEUROSTIMULATION LEADS
First Claim
Patent Images
1. A method of monitoring the position of a neurostimulation lead having at least one electrode, the method comprising:
- taking a baseline evoked potential measurement by supplying a stimulation pulse to tissue with a first electrode on the neurostimulation lead and measuring the resulting evoked potential at a second electrode;
taking a subsequent evoked potential measurement supplying a stimulation pulse to tissue with the first electrode at a subsequent time and measuring the resulting evoked potential at the second electrode; and
determining whether the neurostimulation lead has migrated by comparing the subsequent evoked potential measurement to the baseline evoked potential measurement.
