A ring or rings adapted for endoluminal placement within the stomach, other hollow organ or vessel, and a method for deploying the rings is described. The rings create a small pouch with a reinforced stoma in the stomach for the treatment and control of obesity. An endoluminal suturing device for deploying a circumferential line of interrupted mattress suture bites is inserted into the patient's stomach via the patient's mouth. The distal gastric ring is preloaded on the distal end of the suturing device and is incorporated with suture loops from the double-armed sutures contained within the device. The suturing device can have an expandable area at its distal end that can expand its diameter to between approximately 10 mm and 150 mm. The circumference of this expanded area has a suction opening that is used to draw in tissue when a vacuum is applied to the device. Flexible cannulas containing long flexible suture needles are positioned radially around the circumference of the suction opening. The long needles are are adapted to be advanced through the drawn in tissue incorporating their attached suture material. The expandable area of the device is collapsed, and the device is withdrawn from the patient. With the distal ring anchoring the sutures beneath the incorporated tissue folds, a column of sutures exits the device's suction port as the device is withdrawn. A second, proximal ring is then incorporated with the sutures and may then be endoscopically lowered into the patient's stomach and positioned proximal to the distal ring. The sutures are endoscopically secured and cut, thereby fixing the two rings together with tissue incorporated between them.
