FLEXIBLE STRUCTURES FOR SUPPORTING ELECTRODE ELEMENTS

摘要

An electrode support structure has a guide body (12) having a distal end and a stylet (80) having a bendable portion extending along an axis outside the distal end of the guide body (12). The structure also includes at least one flexible spline leg (22) having a body and a far end extending beyond the distal end of the guide body (12) and attache d to the bendable portion of the stylet (80). The spline leg (22) is normally flexed between the distal guide body end and the bendable styles portion in a first direction that extends along and radially outward of the axis of the stylet (80). At least one electrode element (28) is on the flexible spline leg (22). The bendable styles portion (80) applies tension to flex the spline leg (22) in a second direction.
