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).
Claims18
Surgical ring (1) implantable in a human or animal body, said ring (1) being designed to go around a biological organ constituting a pocket or a duct in order to modify the section of passage of said organ, said ring (1) comprising firstly a belt (2) comprising at least one means (3) for locking said ring (1) in a closed functional position about said biological ring and secondly a flexible inflatable band (10) comprising at least one ring-shaped gripping chamber (12) designed to receive an inflation fluid and comprising at least one aperture (11) enabling the supply therein of inflation fluid, said belt (11) being brought to the flexible inflatable band and fixed to it, said ring (1) being characterized in that the belt (2) comprises a means (14) for placing said at least one aperture (11) of the flexible inflatable band (10) in communication with an inflation fluid supplying means (15).
Surgical ring (1) according to one of the above claims, characterized in that the inflation fluid supplying means (15) comprise a conduit, preferably a catheter.
Surgical ring (1) according to one of the above claims, characterized in that the communications set-up means (14) comprise a fastening means (19) designed to cooperate with the aperture (11) of the flexible inflatable band (10) in order to contribute, at least locally, to the attaching of the belt 2 to the flexible inflatable band 10.
Surgical ring (1) according to one of the above claims, characterized in that the belt (2) has an internal face (2A) with a shape that is substantially complementary to that of the external face (10B) of the flexible inflatable band (10) against which said belt (2) is attached.
Surgical ring (1) according to one of the claims, characterized in that belt (2) is formed by a part made as a single piece comprising firstly on its internal face (2A) the hole (16) and secondly in the extension of one of its ends (4) the conduit (17) so as to form a single-piece belt (2).
Surgical ring (1) according to one of the above claims, characterized in that the flexible inflatable band (10) is formed by a part made as one piece so as to form a single-piece flexible inflatable band (10).
Surgical ring (1) according to one of the above claims, characterized in that it constitutes a gastric ring (1) designed to surround the stomach in order to reduce the section of passage of this stomach, in the context of a treatment for obesity.
Method for manufacturing a surgical ring (1) implantable in a human or animal body, said ring (1) being designed to go around a biological organ constituting a pocket or a duct in order to modify the section of passage of said organ, said method comprising a step for manufacturing a belt (2) comprising at least one means (3) for locking said ring (1) in a closed functional position about said biological ring, a step for manufacturing a flexible inflatable band (10) comprising at least one ring-shaped gripping chamber (12) designed to receive an inflation fluid and comprising at least one aperture (11) enabling the supply therein of inflation fluid, as well as a step for assembling the belt (2) with the flexible inflatable band (10), said belt (2) being brought to the flexible inflatable band (10) and fixed to it, said method for manufacturing being characterized in that the step for manufacturing the belt (2) comprises a sub-step for manufacturing a means (14) for placing said at least one aperture (11) of the flexible inflatable band (10) in communication with an inflation fluid supplying means (15).
