Abstract
Abstract A topical hyperbaric apparatus and method is disclosed. The apparatus comprises a shell having at least one flexible wall portion which provides an external surface and defines a substantially closed internal chamber. The wall portion has an opening therethrough communicating with the internal chamber. The flexible wall portion is sufficiently flexible so as to be capable of conforming to an irregularly shaped surface of a patient's body. An adhesive sealing material is provided on the flexible wall portion for adhesively sealing the shell to the patient's body about the portion to be treated. A gas impermeable liner lines the internal chamber and makes the internal chamber substantially gas impermeable. Therapeutic gases are introduced into the internal chamber to therapeutically treat a portion of the patient's body encompassed by the opening.
