Pouch-equipped intragastric balloon comprising a sealing member which is assembled to the pouches in an improved manner

摘要

The invention relates to an expandable intragastric balloon consisting of: a first flexible pouch (2) comprising a port; a second pouch (20) which contains the first pouch (2) and which is equipped with a hole (21); and a sealing member (4) which is hermetically fixed to the second pouch (20) and which is intended to seal the port and the hole (21). The invention is characterised in that the first and second pouches (2, 20) are produced from different, non-compatible materials and are assembled with the aid of a fixing element (7). According to the invention, the fixing element is designed to ensure that the sealing member (4) is hermetically fixed to the first pouch (2) inside a passage (6) that is defined by a neck (5) which extends from the port, such that sufficient pressure is exerted on the neck (5) in order for same to be pinched between the sealing member (4) and the fixing element (7). The invention is suitable for intragastric balloons.
