System and method for computationally determining migration of neurostimulation leads
First Claim
1. A method performed using a neurostimulation lead having a plurality of electrodes implanted within a patient, the method comprising:
- providing sets of estimated electrical parameter data for estimated lead positions such that each of the estimated lead positions corresponds to a respective one of the sets of estimated electrical parameter data;
transmitting electrical energy using the electrodes;
measuring electrical parameter data that results from the transmitted electrical energy; and
comparing the measured electrical parameter data with the provided sets of estimated electrical parameter data to determine a position of the neurostimulation lead.

Abstract
A tissue stimulation system and computer software and method of monitoring a neurostimulation lead having a plurality of electrodes implanted within a patient (e.g., adjacent the spinal cord) is provided. Neurostimulation lead models are provided, each of which includes estimated electrical parameter data (e.g., electrical field potential data) corresponding to a predetermined position of the neurostimulation lead. Electrical energy is transmitted to or from the electrodes, and electrical parameter data (e.g., electrical field potential data) is measured in response to the transmitted electrical energy. The measured electrical parameter data is compared with the estimated electrical parameter data of each of the neurostimulation lead models, and a position of the neurostimulation lead is determined based on the comparison.
