1. An apparatus for treating an area of biologic tissue comprising:
- a substrate having a substrate surface;
multiple first reservoirs joined with said substrate, said multiple first reservoirs including a reducing agent and a binder material attached with said reducing agent, first reservoir surfaces of said multiple first reservoirs being positioned on said substrate surface, said multiple first reservoirs including a first pattern of reservoirs; and
multiple second reservoirs joined with said substrate, said multiple second reservoirs including an oxidizing agent and said binder material attached with said oxidizing agent, second reservoir surfaces of said multiple second reservoirs being positioned on said substrate surface, and said multiple second reservoirs including a second pattern of reservoirs interleaved with said first pattern of reservoirs to form an alternating arrangement of said first reservoirs and said second reservoirs, said alternating arrangement of said first and second reservoirs defining an active surface of said apparatus, said active surface being adapted to be placed in contact with said area of biologic tissue, and currents are generated between adjacent ones of said first and second reservoirs in said active surface for penetration into said area of biologic tissue;
wherein said binder material in said multiple first and second reservoirs degrades in the presence of an electrolytic solution, wherein degradation of said binder material exposes said reducing agent at said first reservoir surfaces of said first reservoirs and exposes said oxidizing agent in said multiple second reservoirs at said second reservoir surfaces of said second reservoirs.
