  • Patent number: 11207163
    Abstract: A medical device for shutting off a body channel is provided including a band section that can be placed around the body tissue surrounding a body channel and can be closed to form a ring enclosing a passage opening for the body tissue, and has a cavity which makes up one part of a working fluid receiving chamber of the device, for receiving working fluid, and a pump unit for conveying the working fluid. The passage opening is made smaller by introducing the working fluid into the cavity. The arrangement also includes a storage container that has a flexible wall which delimits a storage chamber, wherein to apply an additional force to the body tissue guided through the passage opening, the volume of the storage chamber is made smaller by increasing an ambient pressure acting on the storage container, and the wall of the storage container is at least substantially non-extensible.

  • Patent number: 11197748
    Abstract: A medical device for narrowing or closing an anatomical channel includes a band part (1) which can be placed around the body tissue (2) surrounding the anatomical channel and which can be closed to form a ring that encloses a through-opening (6) for the body tissue, wherein the band part (1) has a hollow chamber (3), and wherein the through-opening (6) can be made smaller by introducing a fluid into the hollow chamber (3). The medical device moreover includes a pump unit (10) which serves to convey the fluid and which has an electric drive (15) controllable by an electronic control system of the device, wherein a pressure value corresponding to the pressure of the fluid in the hollow chamber (3) or dependent on this pressure can be detected by the electronic control system. The device moreover has an air pressure sensor (23) for detecting the atmospheric pressure.

  • Patent number: 11129700
    Abstract: A medical device for shutting off an anatomical channel is provided, including: a band section that can be placed around the body tissue surrounding the body channel and can be closed to form a ring enclosing a passage opening for the body tissue, and that includes a cavity which makes up one part of a receiving chamber of the arrangement, for receiving working fluid; and a pump unit for conveying the working fluid. The passage opening can be made smaller by introducing the working fluid into the cavity. An expansion body is provided having an expansion chamber, and the expansion body is arranged on the band section, on a side of the band section that faces the passage opening, and the expansion chamber can be made bigger by introducing an auxiliary fluid, which is separate from the working fluid, into the expansion chamber.
