摘要

The invention relates to a surgical band which is intended to be implanted in the body of a patient around one or more biological organs such as to form a pouch or conduit which can alter the flow cross-section of the organ when clamped by the band. The inventive band consists of a flexible strip (2) which is designed to be closed essentially at the two ends thereof in order to form a closed loop, said strip (2) comprising an annular compression chamber (7) having a volume that can be adjusted with the injection or removal of fluid. The aforementioned chamber (7) is defined by (i) an inner wall (8A) which is formed by a membrane and (ii) a dorsal wall (8B). The invention is characterised in that the dorsal wall (8B) is formed by a bead comprising an inner face which is located opposite the chamber (7) and which is provided with at least one longitudinal slot. The invention is suitable for restrictive surgical devices.
