Abstract: A multi-prism optical viewing instrument is provided for enabling stereoscopic viewing down tubular and/or deep body channels or cavities, such as the ear canal, nose, vagina, etc., too narrow to permit of viewing with both eyes, and while providing illumination down the channel or cavity without obstruction of the field of view.

Abstract: A method of stopping nose bleeds at the Little's area employs a single-piece flattened strip of material that is inserted into a nostril. The strip has sufficient rigidity to permit the strip to be manually inserted by grasping a lower region between the thumb and fingers, has side surface area sufficient to cover the Little's area, and is flexible enough to conform to the shape of the Little's area. The nose is compressed from the outside into direct engagement with the intermediate region of the strip and thereby clamps the strip against the Little's area in direct conforming pressure-applying engagement with the surface network of the Little's area to terminate bleeding of vessels within the network.
