The invention relates to a sealed container (1) comprising a flange (5, 6) that delimits a through-passage having an axial axis in the container, a door (7) movably mounted on the flange (5, 6), and a first annular seal (13) located between the flange (5, 6) and the door (7), the flange, the door and the first seal forming a sealed connection device that can be connected to a complementary connection device on a sterile enclosure by bayonet connection means in order to allow sterile communication between the sealed container and the sterile enclosure, characterized in that the container (1) includes a protective cover (20) on the connection device, said protective cover being forcibly clipped onto the container, and in that the container further includes contact pressure means arranged between the protective cover (20) and the connection device so as to apply contact pressure to the connection device in the axial direction proportional to the clipping force.

An apparatus includes a plurality of beads, and a linking assembly. Each bead in the plurality of beads includes at least one magnet and a unibody housing encasing and sealing the at least one magnet. The unibody housing includes a magnetically inert material being formed of a particulate powder composition. The linking assembly joins the beads together such that the beads and the linking assembly in arranged in an annular arrangement sized to form a loop around an anatomical structure of a patient. The loop may transition between a contracted configuration and an expanded configuration while being magnetically biased toward the contracted configuration by a magnetic bias of the beads.

An apparatus includes a plurality of beads. Each bead includes a housing and a magnet positioned within the housing. The apparatus also includes a plurality of interconnection elements. Each interconnection element movably joins together a corresponding pair of beads. The plurality of beads and the plurality of interconnection elements are sized and configured to form an expandable loop around an anatomical structure in a patient. The apparatus further includes a decoupling element. The decoupling element is positioned along the loop and is configured to selectively release a first portion of the loop from a second portion of the loop in response to application of a threshold force to the at least one decoupling element in a circumferential direction relative to the loop.
