INTRA-GASTRIC BALLOON WITH DOUBLE-MEMBRANE VALVE AND CORRESPONDING KIT FOR SETTING SAME

摘要

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closing the passageway provided through the paired self-healing membrane (23) when the connecting member has been withdrawn.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.
