GASTRIC RING MADE OF VARIABLE HARDNESS ELASTOMERIC MATERIAL

摘要

- gastroplasty ring of elastomer material with variable hardness. - the invention relates to a gastroplasty ring (1) formed by a flexible strip intended to be closed by closure means around the stomach of a patient, said strip comprising an annular compression chamber (7) connected by a catheter (9) to a device for adjusting the diameter of said chamber by injection or withdrawal of fluid, said chamber comprising a dorsal reinforcement (12) is extended by the lateral walls (13), characterized in that: - the dorsal reinforcement (12) is made from a first elastomer material having a shore a hardness, predetermined d1, - the lateral walls (13) are made from a second elastomer material of the same nature as the first material but having a shore a hardness which is predetermined d2, such that d2 & d1, so as to obtain an annular chamber (7) in one piece with shore a hardness of which is variable in its thickness. - a device for the treatment of obesity.
