    摘要： 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.

    摘要： A sensor probe has a connector and the connector's corresponding receptacle on a console have security mechanisms that ensure that the connector and the receptacle are properly connected and mated. The connector and receptacle can have physical security features that block insertion of the connector into the receptacle if they are not aligned in a proper orientation. The console can also include a software security feature that allows optical measurements from the sensor probe only if the connector of the sensor probe and receptacle on the console are connected properly. An adapter can also be used to convert a conventional receptacle mounted on a console into a receptacle with security features.

    摘要： Methods and apparatus are used to assess the viability of tissue such as flap tissue. According to one aspect of the present invention, a method for assessing the viability of flap tissue includes obtaining an oxygen saturation level associated with a first location on the flap tissue, determining whether the oxygen saturation level is less than a first level, and identifying the first location as having a poor blood supply if the oxygen saturation level is less than the first level.

    摘要： A retractor device has an oximeter sensor at its tip, which allows measuring of oxygen saturation of a tissue being retracted by the retractor. The retractor device also has a force sensor which can measure an amount of force that is applied to the retracted tissue by the tip of the retractor device. The tip includes one or more openings for at least one source and detector. A specific implementation is a spinal nerve root retractor with an oximeter sensor and a force sensor.
