Abstract
Apparatus and methods for detecting lead migration through the use of measured artifactual data about the tissue in the vicinity of the lead.
Claims22
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.
1 more element
A neurostimulation system for use with an implantable lead including at least one electrode, the neurostimulation system comprising:
- a pulse generator including a lead connector;
- circuitry, operably connected to the lead connector, to take a baseline evoked potential measurement associated with a first electrode on the implantable lead and a second electrode and take a subsequent evoked potential measurement associated with the first and second electrodes;
- and
- circuitry to determine whether the implantable lead has migrated by comparing the subsequent evoked potential measurement to the baseline evoked potential measurement.
1 more element
A method of monitoring an individual implanted neurostimulation lead, comprising:
- measuring baseline artifactual data concerning tissue in the vicinity of the individual neurostimulation lead using only the individual neurostimulation lead and an implantable pulse generator;
- measuring subsequent artifactual data concerning the tissue in the vicinity of the individual neurostimulation lead at a subsequent time with only the individual neurostimulation lead and the implantable pulse generator;
- and
- determining whether the individual neurostimulation lead has migrated from a baseline location by comparing the baseline artifactual data to the subsequent artifactual data.
