Abstract: A probe insertable into a body cavity for applying an electrical stimulation to tissue therein includes a flexible hollow member of biocompatible material to enable the member to be inserted into the body cavity and to substantially conform to its inner surface, and thereby, to contact the tissue therein to be stimulated. A portion of the outer surface of the hollow member is electrically conductive to enable an electrical voltage to be applied thereto for electrically stimulating the tissue within the body cavity contacted by the electrically conductive surface. The probe may also include a transparent section and an optical sensor, such as an oximeter, for optically examining tissues within the body cavity.
