Abstract
Devices and systems have a sensor probe configured to measure tissue oxygen saturation in the intestine or mesentery. The devices and systems can determine the oxygenation state of the entire thickness of the intestine or mesentery. Embodiments of the invention also include methods for inducing a temporary ischemic period in an intestine or mesentery tissue and analyzing changes in oxygen saturation of the tissue during the temporary ischemic period or during a recovery phase. The devices, systems, and methods can be applied in diagnosing intestinal ischemia in a patient, as well as in monitoring tissue oxygen saturation of the intestine or mesentery during or after a surgical procedure.
