ABSTRACT:
A gastroplasty ring having a single control is provided and includes a flexible strip with two ends for being closed around the stomach by a closure system so as to reduce the diameter of the opening of the stoma. The strip may have an annular compression chamber of adjustable volume and of substantially constant section connected by an adjustment catheter to a device for adjusting the internal pressure in the chamber so as to adjust its diametral expansion. The closure system may be used for reversibly locking and loosening the ring, and for releasing the diameter of the ring momentarily by relative displacement between the two ends, while continuously forming a closed loop around the stomach. The ring constitutes a gastric implant for treating obesity.
