Abstract
The present disclosure discusses a system and methods for a deep brain stimulation lead. More particularly, the disclosure discusses a stimulation lead that includes one or more silicon based barrier layers within a MEMS film. The silicon based barrier layers can improve device reliability and durability. The silicon based barrier layers can also improve adhesion between the layers of the MEMS film.
Claims18
A neurological lead, comprising:
- an external tube comprising a proximal end and a distal end;
- a planar formed, cylindrical film coupled with the external tube, the planar formed, cylindrical film comprising:
- a plurality of tabs distributed longitudinally along the planar formed, cylindrical film;
- a plurality of ribbon cables, each of the plurality of ribbon cables coupled to two of the plurality of tabs distributed longitudinally along the planar formed, cylindrical film;
- a plurality of electrodes, at least one of the plurality of electrodes disposed on each of the plurality of tabs distributed longitudinally along the planar formed, cylindrical film;
- a plurality of periphery traces, each of the plurality of periphery traces at least partially encircling a perimeter of a respective one of the plurality of electrodes;
- and
- a plurality of contacts, a respective one of the plurality of contacts disposed on each of the plurality of ribbon cables and between the two of the plurality of tabs distributed longitudinally along the planar formed, cylindrical film.
