NOVELTY - A medical battery apparatus (100) comprises first reservoirs (102) joined with a substrate (106), where selected ones of the first reservoirs include a reducing agent; and second reservoirs (104) joined with the substrate, where selected ones of the second reservoirs include an oxidizing agent.    USE - The apparatus is used as a tissue contacting apparatus, wound dressing apparatus, eye contacting apparatus, ear canal insert, intra-vaginal apparatus, internal prosthetic device. It is for application to the area of biologic tissue for treatment including reduction or prevention of infection of the area of biologic tissue. The biologic tissue is from tissue types consisting of skin tissue, epithelial tissue, optic tissue, otic tissue, mucous membrane tissue, connective tissue, muscle tissue, or nerve tissue. The area of biologic tissue includes damaged biologic tissue, inflamed biologic tissue, diseased biologic tissue, and/or infected biologic tissue. It includes condition(s) consisting of an infected traumatic lesion, surgical incision, lesion, wound, cut, puncture, rupture, abrasion, laceration, biopsy site, post-laser treated skin, post-chemical peeled skin, burn, sunburn, frostbite, ulcer, bed sore, rash, contact dermatitis, insect bite, insect sting, snake bite, or animal bite. It includes condition(s) consisting of a bacterial infection, a mycobacterial infection, a yeast infection, a fungal infection, a viral infection, a scar, acne, a blister, a corn, a callus, dermatographia, hives, angioedema, psoriasis, rosacea, scabies, vitiligo, dysplasia, dermatitis, ecthyma, atopic dermatitis, dyshidrosis, neurodermatitis, athlete's foot, a boil, carbuncles, cellulitis, a cold sore, folliculitis, furunculosis, impetigo, jock itch, molluscum conagiosum, herpes, Mucha-Havermann disease, ringworm, shingles, tinea versicolor, actinic keratosis, a wart, freckles, a mole, unusual pigmentation, lipoma, melanoma, scalp cancer, skin cancer, acanthosis nigricans, bullous pemphigoid, epidermolysis bullosa, icthyosis, pityriasis rosea, granuloma annulare, hidradenitis, lichen nitidus, lichen planus, morphea, scleroderma, pilonidial cysts, pyoderma gangrene, Stevens-Johnson syndrome, hemangioma, sweating, body odor, cercarial dermatitis, an ingrown toenail, or a nail fungal infection. (all claimed)    DETAILED DESCRIPTION - A medical battery apparatus comprises first reservoirs joined with a substrate, where selected ones of the first reservoirs include a reducing agent, and where first reservoir surfaces of selected ones of the first reservoirs are proximate to a first substrate surface; and second reservoirs joined with the substrate, where selected ones of the second reservoirs include an oxidizing agent, and where second reservoir surfaces of selected ones of the second reservoirs are proximate to the first substrate surface.    INDEPENDENT CLAIMS are also included for:    (1) a method for treating an area of biologic tissue;    (2) an internal prosthetic device;    (3) a method of manufacturing an apparatus; and    (4) an apparatus comprising a substrate having a first surface and multiple spaced dissimilar reservoirs.    DESCRIPTION OF DRAWING(S) - The figure is a top view of a medical battery having a first configuration of dissimilar reservoirs.
