Patent ID: 7811299

Claim:
A surgically implantable adjustable gastric ring for constricting a tubular organ, the adjustable gastric ring comprising: an open ring body having closure system including a first and a second end parts, the open ring body being designed to be closed around the tubular organ; the closure system constricting the tubular organ by closing the ring and forming the ring into a loop; and the first end part including a first reinforcement flange and a sleeve having a first and a second portions, the sleeve being designed to receive the second end part and having a tab extending from the second portion, the sleeve being disposed in a substantially perpendicular direction in relation to the direction of the first end part, the second part comprising a locking protrusion adapted to engage a first aperture in the sleeve, thereby securing the ring in a closed position; wherein the tab defines a second aperture disposed substantially parallel to the first aperture and includes a second reinforcement flange located adjacent to and in between the first aperture and the second aperture comprises a portion more flexible than the remaining portion of the tab, the flexible portion being situated in the proximity of the aperture, the flexible portion preventing an accidental opening of the closure system after the adjustable gastric ring is disposed around the tubular organ.
