Abstract
A method and apparatus for measuring oxidative metabolism in an internal organ or tissue of interest wherein a percutaneous intravascular approach is utilized to bring a light-transmitting and receiving scope into contact with the site to be assessed. The tip of the scope is adapted so that the light-transmitting optical fiber(s) and light-receiving optical fiber(s) are in divergent relationship so as to increase the photon pathlength through the tissue of interest to provide optical information from a substantial volume of tissue relative thereto.
