METHOD TO ENHANCE ELECTRODE LOCALIZATION OF A LEAD

摘要

An exemplary method includes positioning a lead in a patient where the lead has a longitudinal axis that extends from a proximal end to a distal end and where the lead includes an electrode with an electrical center offset from the longitudinal axis of the lead body; measuring electrical potential in a three-dimensional potential field using the electrode; and based on the measuring and the offset of the electrical center, determining lead roll about the longitudinal axis of the lead body where lead roll may be used for correction of field heterogeneity, placement or navigation of the lead or physiological monitoring (e.g., cardiac function, respiration, etc.). Various other methods, devices, systems, etc., are also disclosed.

1. A method comprising:
positioning a lead body that comprises a longitudinal axis, that extends from a proximal end to a distal end, and electrodes; selecting one or more electrodes at a position along the longitudinal axis and selecting one or more electrodes at another position along the longitudinal axis; measuring electrical potential in a three-dimensional potential field using the selected one or more electrodes at the position and the selected one or more electrodes at the other position; generating data, based at least in part on measurement of electrical potential, for display of a lead direction marquee; and displaying the lead direction marquee.
