Abstract: An intraluminal occluding catheter and method for preventing the loss of gas insufflation from a physiological lumen during a medical procedure is presented. The intraluminal occluding catheter is generally comprised of a catheter shaft having a flexible balloon affixed on a distal intraluminal end and a plurality of independent channels extending through the catheter shaft from the external proximal end to the distal intraluminal end. Once inserted into a physiological lumen such as the bowel, the intraluminal occluding catheter controls the loss of insufflation proximally thereby improving the safety and efficiency of TAMIS as well as allowing for more controlled gas exchange to clear smoke or vapor.
