DUAL BALLOON GASTRIC RING
First Claim
1. Implantable surgical ring designed to be closed on itself to form a closed loop having an extension medium axis for tightening a biological organ forming a pouch or a duct in order to change the cross section of flow into said organ, said ring comprising at least a first ring tightening chamber and a second ring tightening chamber attached to each other and designed to contain a filling fluid for tightening said biological organ by said ring, said first and second tightening chambers being stepped along the extension medium axis of the loop, wherein the first and second tightening chambers include between them a material-free clearance area in which the wall of the biological organ may move without contacting the ring, in order to tighten said biological organ at the level of at least two axially separated contact areas.

Abstract
The invention relates to an implantable surgical ring (1) designed to be closed on itself to form a closed loop (2) having an extension medium axis (XX′) for tightening a biological organ (3), wherein said ring (1) includes at least a first and a second ring tightening chamber (12, 13) attached to each other designed to contain a filling fluid for tightening said biological organ (3), said first and second tightening chambers being stepped along the extension medium axis (XX′), said ring being characterised in that the first and second tightening chambers (12, 13) include between them a material-free clearance area (20), in which the wall of the biological organ (3) may move without contacting the ring (1), in order to tighten said biological organ (3) at the level of at least two axially-separated contact areas (14A, 14B).

- 15. Method for the manufacture of an implantable ring designed to be closed on itself to form a closed loop having a medium extension axis for tightening a biological organ forming a pouch or a duct in order to modify the cross section of flow of the opening into said organ, said method comprising a preparation step (a) during which at least one ring tightening chamber and a second ring tightening chamber are created, each designed to contain a filling fluid, a step (b) involving stepping during which said first and second tightening chambers are mechanically connected to each other being stepped along the extension medium axis of the loop, said method characterised in that the step (b) involving stepping comprises a delimitation sub-step during which said a material-free clearance area is made between the first and second tightening chambers clearance area in which the wall of the biological organ may move without contacting the ring, so that the first and second tightening chambers tighten the biological organ at the level of at least two axially separated contact areas.
