Abstract: A surgical ring is suitable for implantation in a human or animal body and to surround a biological organ forming a bag in order to modify the flow area thereof. The ring comprises a hose having an inner surface intended for engaging with the biological organ in order to modify the section thereof and an outer surface opposite the former, and a belt mounted on and along the outer surface and attached to the latter. The hose and the belt are respectively provided with a first and second matching assembly that interact mechanically in order to substantially prevent any sliding of the belt along the outer surface.

The invention can be used in the field of implantable medical devices.

Abstract: An implantable device (1) for injecting and/or drawing fluid either in an organ or vessel of the body of a human or animal patient and the device comprising a housing (2) with a chamber (2A) connected to a catheter, the catheter is connected either to the organ or vessel or to the compartment. The housing (2) has a proximal wall (4) and a distal wall (5) between which a lateral wall extends. The housing (2) has a puncture area (7) able to be pierced by a hollow needle (14) for injecting and/or drawing fluid in the chamber (2A). The puncture zone (7) extends on the proximal wall (4) and the lateral wall.

Abstract: The invention relates to an expandable intra-gastric balloon (1) for treating obesity, the balloon being for implanting in the stomach in order to reduce its volume, said balloon (1) comprising a first flexible pouch (2) provided with first connection means (3) for receiving a connection member (6) that is for connection to a first fluid source in order to expand said first pouch (2) in the stomach by filling it with fluid, the balloon being characterized in that it includes at least one second flexible pouch (20) provided with second connection means (3?), said second connection means (3?) being separate from the first connection means (3) in such a manner as to be capable of being connected to a second fluid source different from the first fluid source. The invention applies to treating obesity.

Abstract: An implantable device (1) for injecting fluid and/or for tapping fluid, the device having a housing (3) provided with a puncture zone (4) able to be transpierced by a hollow needle (5) for injecting fluid into and/or tapping fluid from a chamber (3A) provided inside the housing (3). The implantable device has a puncture zone (4) made up of at least first and second superposed flexible membranes (6, 7) mounted to be free, at least locally, relative to each other, to allow the membranes, at least locally, to move along each other, so that, once the needle (5) has been removed, the orifice formed by the needle (5) is sliced into first and second sub-orifices (6A, 7A) substantially not coinciding so as to impart a substantially leaktight property to the puncture zone (4).

Abstract: The invention relates to an implantable surgical ring (1) to go around a biological organ and constituting a pocket or duct designed for adjustment of the section through which said organ passes, said ring (1) including a belt (2) comprising at least one locking means (3) for said ring (1) in the closed functional position thereof around said biological organ and a flexible inflatable band (10) comprising at least one opening (11) enabling the supply therein of an inflation fluid, said belt (2) being fitted with the flexible inflatable band (10) and attached to the latter, said ring being characterized in that the belt (2) includes a coupling means (14) for coupling said at least one opening (11) of the flexible inflatable band (10) with an inflation fluid supplying means (15).

Abstract: The invention relates to an implantable medical device designed for the injection and/or removal of a fluid substance into and/or from a human or animal body, said device comprising a housing (2) provided with a chamber (3) that extends between a first end and a second end and that is delimited by a side wall (6) which joins said first end to said second end, said side wall (6) having at least a first puncture zone (10) and a second puncture zone (11), said device comprising a non-pierceable screen (13), said device being characterized in that the side wall (6) is formed in one piece, and in that a portion of the non-pierceable screen (13) is inserted into a blind seat (14) formed within the thickness of said side wall (6). Implantable medical devices.

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).

Abstract: A kit for introducing an intragastric implant. The kit comprises an intragastric implant for implanting in the stomach. The implant is expandable from a configuration for introduction into the stomach to a therapeutic configuration within the stomach. The kit further includes a cartridge for packaging said implant in the introduction configuration. The cartridge is provided with an opener member activatable by positive action enabling it to depart from a closed configuration. The cartridge includes locking means functionally connected to the opener member and capable on its own, without any external action on said locking means of holding the cartridge in the closed configuration. The intragastic implant may be used 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: 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.
