摘要： A medical device such as an oximeter includes a marking feature. In an implementation, a marking mechanism of the device marks tissue based on a location of where a measurement was taken by the device. In an implementation, the marking mechanism of the device marks tissue based on an oxygen saturation measurement obtained by the device.

摘要： A retractor system with a closed loop control includes a retractor having one or more sensors, which measure parameters associated with a retracted tissue. The system further includes a positioning mechanism connected to the retractor and a controller which receives feedback signals from the sensors. Based on the feedback signals from the sensors, the retractor is actuated by the positioning mechanism so that the tissue can be retracted while maintaining the parameters associated with the retracted tissue above a threshold level or within a desired range. Another retractor system includes a retractor with a force sensor and at least one additional sensor, which can be used without a closed loop control arrangement.

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： 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.
