1. A magnetic occluding device for a conduit in a body comprising:

  • first and second assembles, said assemblies including means for mounting the assemblies on opposite sides of a bodily conduit;

    at least a first of said assemblies including magnet means having a pair of poles that are spaced apart in a reference direction passing through the poles, said magnet means being movably mounted on the first assembly for movement between first and second positions, the reference direction of the poles being substantially transverse to the conduit in one of said positions;

    a second of said assemblies including means that are magnetically attracted to the poles of the magnet means in a first position of the magnet means the magnet attraction between the two assemblies is substantially reduced to permit a bodily conduit placed between the assemblies to expand, the magnet means being movable between the first and second positions in a direction parallel to a plane defined by the second assembly; and

    means for actuating the magnet means between the first and second positions.
