Systems and methods for guiding movable electrode elements within multiple-electrode structures

摘要

Systems and related methods guide a movable electrode (36) within an array of multiple electrodes (24) located within the body. The systems and methods employ the movable electrode (36) or at least one of the multiple electrodes (24) on the array to generate and then sense electrical or sonic energy in a predetermined fashion to generate an output that locates the movable electrode (36) within the array.
