Abstract:
1. An occluding device for closing a body passage, the occluding device comprising: an occluding body, a first position control element, and a second position control element, wherein the occluding body is a balloon made of a flexible and fluid tight material without a shape memory property, the balloon comprising a distal chamber, a proximal chamber, and a connecting channel connecting the two chambers, a proximal end of the occluding body being fluid-tightly attached to the first position control element, and a distal end of the occluding body being fluid-tightly attached to the second position control element, the first position control element and the second position control element being two mating parts of a fluid tight closure of the balloon closing an interior of the balloon so that the interior is fluid tight, the occluding body being compressible into a first longitudinal shape, the occluding body being adapted to be brought into a second inflated shape by introduction of a fluid and into a third radially extended but longitudinally compressed shape by evacuating the fluid and by bringing the two position control elements into a snapped together position, wherein no additional stiffening means are present in the occluding device to obtain the third radially extended but longitudinally compressed shape, and wherein no additional stiffening means for stiffening the balloon in its third radially extended but longitudinally compressed shape are arranged within the balloon, and wherein the two position control elements form an open passage through the balloon in the third shape.
