Abstract: The invention relates to a gastroplasty ring formed by a flexible strip (2) for passing around the stomach and for being closed near its two end portions (5, 6) by a closure system (7, 12, 13, 15, 20) to reduce the diameter of the opening of the stoma, said strip having an annular compression chamber of adjustable volume and of substantially constant section that is connected by an adjustment catheter (7) to a device (8) for adjusting the internal pressure in said chamber so as to adjust its diametral expansion, the ring being characterized in that the closure system includes means (12, 13) for locking and loosening the ring, which means are carried by the adjustment catheter, thus making it possible, starting from the position in which the diameter of the ring is locked, to release the diameter of the ring by relative displacement between the two end portions. The ring constitutes a gastric implant for treating obesity.

Abstract: A gastroplasty ring having a single control is provided and includes a flexible strip with two ends for being closed around the stomach by a closure system so as to reduce the diameter of the opening of the stoma. The strip may have an annular compression chamber of adjustable volume and of substantially constant section connected by an adjustment catheter to a device for adjusting the internal pressure in the chamber so as to adjust its diametral expansion. The closure system may be used for reversibly locking and loosening the ring, and for releasing the diameter of the ring momentarily by relative displacement between the two ends, while continuously forming a closed loop around the stomach. The ring constitutes a gastric implant for treating obesity.

Abstract: A gastroplasty band, as disclosed herein, comprises a flexible strip designed to be closed around the stomach of a patient by a closure mechanism. The flexible strip includes an annular compression chamber connected by a catheter to a device for adjusting the diameter of the compression chamber by injecting or withdrawing fluid. The compression chamber comprises a dorsal reinforcement extended by lateral walls. The dorsal reinforcement is made out of a first elastomer material having predetermined hardness d1 on the Shore A scale. The lateral walls are made out of a second elastomer material of the same kind as the first elastomer material but of predetermined hardness d2 on the Shore A scale such that d2<d1. The annular compression chamber thus has a hardness on the Shore A scale that varies across its thickness.

Abstract: An injection device (1) for injecting medical substances and designed to be implanted in a subcutaneous zone of the body of a patient. The device includes a hollow rigid housing (2) having an opening which is closed hermetically by a membrane (3) so as to define a chamber (12). A duct (4) is connected to the housing to connect the chamber to the outside of the device. The device also has a casing (15) of elastomer material which covers the housing, and the membrane forms an integral portion of the casing. The implantable device is suitable for performing chemotherapy treatment.

Abstract: This appliance comprises, in a tubular body (20), a magazine slide (22) secured to a needle (50) and the magazine slide (22) containing fasteners (A), an element for distributing the fasteners one by one, and an ejection plunger (42) able to push the anchoring bar (2) of the awaiting first fastener (A) into the needle. According to the invention, the magazine slide (22) comprises below the needle (50) a transverse finger (59) able, as the fastener is distributed by movement of its anchoring bar (2) by the plunger (42), to have the downstream end (3a) of this catching bar bear against it to force it to pivot by raising its upstream end (3b), beside the needle (50), a downwardly projecting rib (51) able to guide the pivoting of the upstream end (3b) of the catching bar (3) so that the latter does not butt against the needle, and, on the transverse finger (59), a sloping face (59a) driving the downstream end (3a) of the catching bar (3) transversely away from this finger.
