TECHNICAL FIELD [0001] The present invention relates to the technical field of surgical implants intended to treat obesity by implanting a flexible gastric band intended to restrict the stomach of a patient, said gastric band being equipped with an annular compression chamber, the volume of which is variable and can be adjusted via an adjusting catheter connected to an adjusting and control device implanted in the body of the patient. [0002] The present invention relates to a gastroplasty ring formed by a flexible band which comprises a first end part and a second end part and which is intended to be closed around the stomach essentially toward and by its two ends, using a closure system so as to reduce the diameter of the opening of the stoma by forming a loop, the band comprising an adjustable-volume annular compression chamber connected, at one of the end parts, by an adjusting catheter to a device for adjusting the internal pressure of said chamber, so as to adjust its diametral expansion. PRIOR ART [0003] In the case of patients suffering from extremely severe obesity (morbid obesity), that is to say in the case of patients whose weight exceeds the ideal weight by at least fifty kilos, for example, it is absolutely essential to treat these patients surgically in order not only to avoid a series of health problems ensuing from this obesity, but also to avoid certain and precipitate death of such patients. [0004] Indeed, it is acknowledged that patients suffering from morbid obesity present a significantly reduced life expectancy, the reduction being by at least some ten to fifteen years, while at the same time creating significant problems of physchological burden. Furthermore, a whole series of ancillary health phenomena are involved, having an impact on the development of cardiovascular diseases, hypertension, diabetes, and severe arthritis in particular. [0005] It has been found that treatment based on a strict diet combined with a series of physical exercises associated with a modification in behavior, particularly eating habits, were not very well suited to such cases of morbid obesity, even though such treatment methods are the most healthy. [0006] This is why treatments for morbid obesity which are effective and remain so in the long-term, involve surgical treatment. [0007] In general, a distinction is made between surgical treatment techniques involving a lack of absorption of foodstuffs, that is to say a shortening of the conventional path of the food and of the digestive juices, and techniques involving gastric restriction, reducing the size of the stomach. [0008] Surgical techniques involving a lack of absorption are, for example, those involving a technique of bypassing the small intestine or alternatively those separating the passage of the foodstuffs relative to the digestive juices. The surgical technique of bypassing may give rise to severe complications, which means that this technique is now used only very rarely. The surgical technique of separating the passage of the alimentary bolus relative to the digestive juices does not involve particular complications, but entails a major surgical operation involving, in particular, a partial gastrectomy. [0009] This is why the trend nowadays is to use surgical techniques employing gastric restriction to reduce the intake of food. [0010] Such techniques conventionally involve the use of gastroplasty rings implanted around the stomach in order to reduce its size and the diameter of its passage (stoma). [0011] Most of the known gastroplasty devices, and, for example, the one described in U.S. Pat. No. 5,074,868, employ a flexible band made of an elastomeric material and intended to be implanted around the stomach then tightened and closed into a loop of fixed diameter by a closure system. The body of the flexible band contains a variable-volume compression chamber or cavity connected by an adjusting catheter to a device for adjusting the internal pressure of the chamber so as to vary the inside diameter of the loop in order to modify or adjust the diameter of the stoma by injecting or extracting a volume of liquid into or from the chamber. Such an operation of adjusting the inside diameter of the ring is performed using conventional control devices including a miniaturized unit implanted directly under the skin of the patient and equipped with a self-sealing membrane through which the doctor injects or withdraws liquid using a syringe. [0012] The closure system of U.S. Pat. No. 5,074,868 employs suturing, using sutures, of the two parts of the flexible band of the ring. [0013] Such a device is generally satisfactory but, like most of the known systems, suffers from disadvantages associated essentially with the difficulty involved in any surgical operation likely to arise once the gastroplasty implant has been fitted. What has been found is that in spite of the possibility of, to a certain extent, altering the diameter of the ring without surgical intervention, using the miniaturized unit mentioned hereinabove, the fitting of such gastric implants may be accompanied by phenomena of intolerance, for example accompanied by vomiting, associated with an excessive reduction in the diameter of the stoma, or alternatively with ineffective action of the implant associated with an excessively large diameter of the stoma, or alternatively still, quite simply with discomfort or a local or generalized infection or inflammation. [0014] This is why it is often necessary to perform a further surgical operation, either to make the patient more comfortable, or to modify or change the gastroplasty ring already implanted. Such surgical operations are particularly severe and in addition entail either a surgeon cutting the ring, or the cutting of the suture accompanied by a complete opening of the ring followed by its exchange and replacement. [0015] Such operations are tricky to perform, are difficult for the patient to tolerate, and are therefore expensive in that they entail destroying an implant and replacing it. SUMMARY OF THE INVENTION [0016] The object of the invention is therefore to propose a novel gastroplasty ring making it possible to remedy the various drawbacks listed above and which is capable of making the ring easier to handle when the implant is being fitted and when the ring is being opened and closed again during a further operation. [0017] Another object of the invention is to propose a novel gastroplasty ring capable simply and reliably of reversibly closing the loop that makes up the ring while at the same time allowing easy unlocking of the end parts, doing so without entailing destruction of the implant. [0018] Another object of the invention is to propose a novel gastroplasty ring capable of offering a simple and reliable means of adapting the diameter of the ring to suit each given surgical situation. [0019] Another object of the invention is to propose a novel gastroplasty ring capable of exhibiting several implantation diameters. [0020] Another object of the invention is to propose a novel gastroplasty ring making it possible to reduce the discomfort experienced by the patient, while at the same time being firmly held in place by the loop. [0021] Another object of the invention is to propose a novel gastroplasty ring which is particularly easy to manufacture while at the same time having excellent overall mechanical strength.
