The balloon (1) is characterised in that it includes means for configuring same in an extraction configuration (10), said means exerting a stress on the intragastric balloon (1) such that it changes from the deployed configuration to a third noticeably-smaller contracted volume configuration, known as the extraction configuration, by acting on the outer casing (3) such that the casing (3) essentially returns to or towards a predetermined shape corresponding to the extraction configuration. The invention is suitable for intragastric balloons.

The invention relates to an implantable device (1) for injecting and/or drawing fluid comprising, on the one hand (2) and, on the other, a puncture wall (3) added to said hollow body (2) so that the hollow body (2) and puncture wall (3) delimits a chamber (4), said puncture wall (3) being designed for being transfixed by a hollow needle for injecting and/or drawing the fluid into the chamber (4), said device (1) being characterized in that it comprises a means for fixing (8) the puncture wall to the hollow body (2) so that the hollow body (2), puncture wall (3) and fixing means (8) form a single subassembly (9), and an enclosure (10) essentially covering the puncture wall (3). Disclosed are implantable medical sites.

Abrégé

The invention concerns an intra-gastric balloon comprising: at least one bag adapted to be filled with an inflating fluid; connecting means (3) comprising a self-sealing member (21) adapted to be perforated by a connecting member to an inflating fluid source. The invention is characterized in that the self-sealing member (21) comprises at least two superimposed self-healing membranes (23), forming paired self-healing membranes (23), adapted to be successively perforated by the connecting member, each self-healing membrane (23) being mounted so as to be urged to press against the paired self-healing membrane (23) so as to form a sealing barrier for automatically closing the passageway provided through the paired self-healing membrane (23) when the connecting member has been withdrawn. The invention also concerns an intra-gastric balloon for treating obesity.

Abrégé

The invention concerns an intra-gastric balloon designed to be implanted inside a patient's stomach to reduce the stomach volume in a treatment of obesity, said intra-gastric balloon (1) comprising: at least one bag (2) adapted to be filled, at least partly, with an inflating fluid; connecting means (3), mounted on said bag (2) and adapted to receive a connecting member (11) to an inflating fluid source. The invention is characterized in that the connecting means (3) comprises a chamber (16) designed to be perforated by said connecting member (11) to inject the inflating fluid into said bag (2), said chamber (16) containing a sealing fluid sufficiently viscous and/or consistent to seal the connecting means (3) when the connecting member (11) has been withdrawn. The invention also concerns an intra-gastric balloon for treating obesity.

Abrégé

The invention concerns an intragastric balloon (1) for treating obesity designed to be implanted in a patient's stomach to reduce the stomach volume, said balloon (1) being delimited by a surface envelope (3) and characterized in that at least one fraction (6, 7) of said surface envelope (3) is associated with a reinforcement (8), to form a reinforced portion designed to extract the balloon (1) out of the stomach by gripping the reinforced portion with an endoscopic extracting tool (2). The intragastric balloon is useful for treating obesity.
