Abstract: Devices, systems, and methods for detecting a fluid infiltration event. A system includes a fluid delivery cannula having a distal end and a proximal end, a fluid source fluidly coupled to the proximal end of the fluid delivery cannula, and an optical sensor optically coupled to an interior of the fluid delivery cannula. The optical sensor is disposed between the distal end and the proximal end of the fluid delivery cannula and configured to generate an electronic signal based on one or more characteristics of light sensed in the interior of the fluid delivery cannula when fluid from the fluid source is passed therethrough. The system further includes a controller configured to receive the electronic signal from the optical sensor and determine a fluid infiltration event based on the electronic signal.
