Combined micro-macro brain stimulation lead has micro segment movable in macro segment between retracted position, deployed position extending through macro segment opening

摘要

The combined micro-macro brain stimulation lead (10) has a macro segment with an opening (50) and a micro segment (70) arranged to be movable within the macro segment between a retracted position, in which it is insider the macro segment, and a deployed position, in which it extends through the opening in the macro segment. The macro segment has at least one electrode near the opening.
