ABSTRACT:
A magnet system for sealing devices for artificial or natural intestinal or similar ducts, comprising a ring-magnet to implant in the tissue around the duct and a rod-shaped center magnet member mounted in a more or less soft sealing member to be in sealing contact with the walls of the duct. The improvement is that the center magnet member comprises at least two, in practice usually two or three, axial aligned individual magnets acting together so as to resist axial displacement; the individual poles are positioned to resist tilting of the center magnet member relative the axis of the duct and the ring-shaped magnet member.
