System for determining relative position between neurostimulation leads
First Claim
1. A medical system for use with electrode leads, comprising:
- memory configured for storing a first reference electrical profile for the electrode leads in a first known staggered configuration, the first reference electrical profile containing a plurality of reference cross-electrode lead electrical parameters; and
at least one processor configured for generating instructions to measure a plurality of cross-electrode lead electrical parameters, generating a measured electrical profile of the electrode leads from the measured cross-electrode lead electrical parameters, spatially shifting the first reference electrical profile to generate a second reference electrical profile for the electrode leads in a second known staggered configuration, comparing the measured electrical profile to the first and second reference electrical profiles, and quantifying a longitudinal stagger between the electrode leads based on the comparison.

Abstract
A method and neurostimulation control system for operating two leads disposed adjacent tissue of a patient are provided. A plurality of cross-lead electrical parameters are measured to generate a measured electrical profile of the electrode leads. A plurality of cross-lead electrical parameters are estimated to generate a first reference electrical profile for the electrode leads in a first known staggered configuration. The first reference electrical profile is spatially shifted to generate a second reference electrical profile for the electrode leads in a second known staggered configuration. The measured electrical profile is compared to the first and second reference electrical profiles, and a longitudinal stagger between the electrode leads is quantified based on the comparison.
