| abstract |
The invention relates to a device for the implantation of occlusion helixes ( 3 ) into body cavities or blood vessels, in particular aneurysms ( 12 ), with at least one occlusion helix ( 3 ) comprising a plurality of windings and being movably arranged in longitudinal direction within a catheter ( 1 ), and one securing means ( 9 ) passing at least partially through the lumen of the occlusion helix ( 3 ), with said securing means ( 9 ) being fixed in its end areas inside the occlusion helix ( 3 ) and consisting of at least two wires with each of the wires having a diameter of less than 0.02 mm. The use of a plurality of wires of relatively small diameter for the securing means ( 9 ) enables high flexibility and at the same time high tensile strength properties to be attained. In this way, two opposed characteristics can be achieved which at first glance appear to be mutually exclusive. |
