There is provided a method for controlling a flow of fluid and/or other bodily matter in a lumen formed by a tissue wall of a patient's organ. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the flow in the lumen, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the lumen. The method can be used for restricting or stopping the flow in the lumen, or for actively moving the fluid in the lumen, with a low risk of injuring the organ. Such an organ may be the esophagus, stomach, intestines, urine bladder, urethra, ureter, renal pelvis, aorta, corpus cavernosum, exit veins of erectile tissue, uterine tube, vas deferens or bile duct, or a blood vessel. |

1. A method for controlling a flow of fluid and/or other bodily matter in a lumen formed by a tissue wall of a patient's organ, the method comprising the steps of:
inserting a needle like tube into a cavity of the patient's body, using the needle like tube to fill the cavity with gas thereby expanding the cavity, placing at least two trocars in the patient's body, inserting a camera through one of the trocars into the cavity, inserting a dissecting tool through any of the trocars and dissecting an area of at least one portion of the tissue wall of the patient's organ, placing a constriction device and a stimulation device in the dissected area in operative engagement with the patient's organ, using the constriction device to gently constrict the at least one portion of the tissue wall portion of the patient's organ to influence the flow in the lumen, and using the stimulation device to stimulate the constricted at least one portion of the tissue wall portion of the patient's organ to cause contraction of the wall portion to further influence the flow in the lumen. |
