ELECTRODE AND LEAD STABILITY INDEXES AND STABILITY MAPS BASED ON LOCALIZATION SYSTEM DATA

摘要

A method includes selecting an electrode located in a patient wherein the electrode comprises a lead-based electrode; acquiring position information with respect to time for the electrode, during both loaded and unloaded conditions of the lead, where the acquiring uses the electrode for repeatedly measuring electrical potentials in an electrical localization field established in the patient; calculating a both loaded and unloaded stability metrics for the electrode based on the acquired position information with respect to time; and comparing the unloaded and loaded stability metrics to decide whether the electrode, as located in the patient, comprises a stable location for delivery of therapy.
