System and method for computationally determining migration of neurostimulation leads

摘要

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.

1. A method of monitoring a neurostimulation lead having a plurality of electrodes implanted within a patient, the method comprising:
providing a plurality of sets of estimated electrical parameter data, each set corresponding to a predetermined relative position of the neurostimulation lead; transmitting electrical energy to or from the electrodes; measuring electrical parameter data in response to the transmitted electrical energy; comparing the measured electrical parameter data with the estimated electrical parameter data of each of the sets; and determining a position of the neurostimulation lead based on the comparison.
