A medical implantable occlusion device (100) is disclosed comprising a braiding of at least one thread, an expanded diameter portion (102), and a tubular member (103) having a distal endpoint closest to the expanded diameter portion having a distal rim (107). The braiding comprises a stem (108) having a first end connected to the expanded diameter portion and a second end connected to the distal region, where the stem in a relaxed state is partly sunk into the tubular member beneath the distal rim (107), wherein the proximal region comprises a connecting member (113), wherein ends of the at least one thread are fixed to the connecting member, the expanded diameter portion comprises returning loops of the at least one thread whereby opposite ends of the at least one thread forming the expanded diameter portion are fixed to the connecting member. |

1. A medical implantable occlusion device comprising a braiding of at least one thread, said braiding having an unloaded relaxed state and a stretched state and comprising, in said unloaded relaxed state,
an expanded diameter portion, a tubular member extending along a longitudinal axis, said tubular member having a distal region towards said expanded diameter portion and an opposite proximal region, wherein a distal end of said distal region forms a distal rim at a distal end of the tubular member and a proximal end of said proximal region forms a proximal rim at a proximal end of the tubular member, and wherein said tubular member tapers continuously inwardly from said proximal rim to said distal rim and towards said longitudinal axis, and, a stem having a first end directly connected to said expanded diameter portion and a second end directly connected to said distal region, wherein said stem in said relaxed state is partly sunk into said tubular member beneath said distal rim whereby said second end of said stem is displaced from said distal rim by a first offset along said longitudinal axis, wherein said proximal region comprises a connecting member for a delivery device, wherein ends of said at least one thread are fixed to said connecting member, and wherein said expanded diameter portion comprises returning loops of said at least one thread whereby opposite ends of said at least one thread forming said expanded diameter portion are fixed to said connecting member being the connection point for said opposite ends. |
