Embodiments of the present invention relate to systems, devices, and methods for delivering distending media to an organ of a patient with a dispensing device for acquiring an image of the organ while distended. In one embodiment, an insufflating device comprises a controller for detecting a pressure level of the distending media within an organ of a patient, wherein the controller is configured to signal an operator to acquire an image of the organ when the pressure level is within a predetermined pressure range for a predetermined period of time. Further, the insufflating device comprises a valve assembly in communication with the controller and in fluid communication between the source of distending media and the organ of the patient, wherein the valve assembly is configured to adjust a flow rate of the distending media delivered to the organ of the patient.

The insufflating system according to claim 1, wherein the controller is configured to, after detecting the final target insufflation pressure level, monitor a pressure level of the distending media within the colon of the patient and to provide an indication that proper distension has been achieved for acquiring an image of the colon based on the monitored pressure level being within a predetermined pressure range for a predetermined period of time. 5. The insufflating system according to claim 4, wherein the controller is further configured to detect at least one predetermined volume level of the distending media delivered to the colon, and wherein the controller is configured to provide an indication that proper distension has been achieved for acquiring an image of the colon of the patient based on the detected pressure level being within a predetermined pressure range for the predetermined period of time and the at least one detected volume level. 6. The insufflating system according to claim 1, further comprising a relief valve in communication with the controller, wherein the controller is further configured to actuate the relief valve in order to vent the distending media from the colon. 7. The insufflating system according to claim 1, further comprising a wireless remote configured to communicate with the controller for controlling operation thereof. 8. The insufflating system according to claim 1, further comprising a relief valve assembly in communication with the controller, wherein the relief valve assembly is configured to vent the distending media in response to detecting a predetermined pressure threshold for a predetermined period of time. 9.
