1. A device for generating an artificial constriction in a gastrointestinal tract, the device comprising:
- a band adapted to be placed annularly about a particular portion of the gastrointestinal tract, said band comprising a fillable hollow volume and a pair of end regions; and
a safety closure device for connecting said end regions of said band placed annularly about the portion of the gastrointestinal tract, said safety closure device being operable to automatically open without destruction at a tear-off tension exceeding a limit value and operable to be closed again after opening,wherein the limit value of the tear-off tension is in a range between 20 and 60 N, andwherein said safety closure device comprises a cross piece having a circumferentially closed insertion opening, said cross piece being secured on a first of said end regions of said band, an extension insertable through the circumferentially closed insertion opening on said cross piece, said extension extending from a second of said end regions of said band and having a projection extending on a side of the cross piece facing away from said second end region when said safety closure device is closed, and a pull strap provided with said extension, said pull strap extending further way from said cross piece than said projection.

Abstract
A device for generating an artificial constriction in a gastrointestinal tract includes a band, which can be placed annularly about a particular portion of the gastrointestinal tract, having a fillable hollow volume, and a closure device for connecting end regions of the band placed annularly about the portion of the gastrointestinal tract. The closure device is a safety closure, which, at a tear-off tension exceeding a limit value, opens free of destruction, and which can be closed again. This limit value of the tear-off tension is in the range between 20 and 60 N, and preferably between 30 and 50 N.
