Abstract: Ring comprising: an outer belt (3) equipped with closing means (7) for closing the ring (1) around a duct (2); an inner chamber (4) that can be inflated and deflated; a flexible inflation/deflation tube (5); wherein the lips have contact surfaces facing each other, the closing means comprising at least one perforation arranged on the contact surface of a first of the two lips and at least one protrusion protruding from the contact surface of a second of the two lips, the protrusion and the perforation being configured so that the protrusion is retained in the perforation by fitting, the fitting being selected to be released in the event of overpressure in the ring.

Abstract: A device for implanting an inflatable intra-gastric balloon for implanting the intra-gastric balloon into a stomach, comprising: —an elastically deformable sheath configured to receive the intra-gastric balloon in the deflated state, the sheath comprising a side wall, —a tube configured to be supplied with a fluid and to cause the fluid to inflate the intra-gastric balloon, the tube comprising a mouthpiece, the intra-gastric balloon being attached to the mouthpiece in the deflated state and being detached from the mouthpiece in the inflated state, the mouthpiece having an inflation position wherein the mouthpiece extends in the cavity of the sheath, and the side wall of the sheath having a side opening configured to release the intra-gastric balloon from the cavity when the intra-gastric balloon moves from the deflated state to the inflated state.

Abstract: The invention relates to a perivascular ring having an inner diameter adjustable by inflation/deflation and adapted to be implanted and closed about a vessel for controlling the inner diameter of said vessel and thus the flow and/or pressure of a fluid flowing in said vessel. The ring of the invention is capable of regulating blood flow to the liver, in particular after an hepatectomy or hepatic transplant, and to substantially improve the survival chances of the patient. The ring according the invention has an adjustable inner diameter (Øi) for implantation and locking about a vessel.

Abstract: The invention relates to a non-inflatable gastric band (1) including two end areas (2, 3) and an intermediate portion (4). The inner surface (I) of the band (1) is intended to contact the stomach. The end areas (2, 3) are provided with complementary closing means (5, 6) selected from notches (5) and locking loops (6) that are mutually engageable so as to ensure that the band (1) is locked in a closed position. The end area (2) has at least one notch (5) and is intended to be inserted through at least one locking loop (6) placed on the outer surface of the end area (3) up to a locked closed position, wherein at least one notch (5) is moved beyond a locking loop (6). The end area (3) also includes a guide loop (7).
