Abstract
A probe useful for invasively monitoring the oxygen saturation level of blood in the tissue walls of an anatomical canal generally includes a chassis with an electrical connector extending from the proximal end of the chassis and terminating at a plug configured for connection to a pulse oximeter box. The probe further includes an optics assembly configured to generate and transmit electrical signals that are indicative of the dynamic oxygen saturation level of blood in the wall tissue. The probe further includes a deployment device attached to the chassis for biasing the optics assembly into the tissue wall of the anatomical canal.
