Abstract

In one embodiment, a surgically implantable adjustable ring comprises a ring body, which includes a closure system having first and second end parts. The ring body is designed to be closed around a tubular organ by the closure system, constricting the tubular organ by forming a loop. The first end part is shaped like a sleeve having a first and second end portions, and is designed to receive the second end part of the ring. The sleeve is substantially perpendicular to the main direction of the first end part of the ring, and the second end part of the ring includes a locking protrusion adapted to hold the sleeve in position, securing the ring in a closed position by engaging the locking protrusion in an opening disposed on the sleeve.

Claims

1. A surgically implantable adjustable ring for constricting a tubular organ, the adjustable 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 sleeve having a first and a second portions, the sleeve being designed to receive the second end part, 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 an aperture in the sleeve, thereby securing the ring in a closed position.

2. The adjustable ring according to claim 1, wherein the second portion of the sleeve contains the aperture, and wherein the second portion of the sleeve partially overlaps the the second part when the ring is in the closed position.

3. The adjustable ring according to claim 2, the first end part further comprising a reinforcement structure.

4. The adjustable ring according to claim 1, further comprising a tab extending from the second portion of the sleeve.

5. The adjustable ring according to claim 4, wherein the tab 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 ring is disposed around the tubular organ.

6. The adjustable ring according to claim 5, wherein said flexible portion comprises an opening.

7. The adjustable ring according to claim 3, wherein the reinforcement structure comprises a flange disposed transversally to the external perimeter of the ring.
