Abstract
A device for measuring incident light in a remote situs such as a body cavity which includes a central tubular member through which light is delivered to the remote situs and one or more auxiliary tubular members through which incident light in the remote situs is transmitted to a light detector. Each auxiliary tubular member receives incident light from a different portion of the remote situs. The apparatus is particularly useful for conducting phototherapy in body cavities and has been demonstrated in the phototherapy treatment of superficial cancer in a bladder.
