Filling material for treating chronic venous insufficiency and a corresponding insertion method

A device applicable to insertion into a vein of a human patient,

• wherein the device is a tubular device and it comprises:
• a control cable made of metal, which is insertable into the vein,
• a sheath with an inner and outer part, the inner part of the sheath having a central tunnel for the control cable, where the inner and the outer parts of the sheath are able to slide in relation to one another and in relation to the control cable into the vein and inside the vein,
• two-sidedly adhesive tubular material between the inner and outer parts of the sheath, where
• the diameter of the two-sidedly adhesive tubular material is expandable either in self-acting fashion or as a response to pressure originating from inserted liquid inside the tubular material after the outer part of the sheath has been removed, when the outer adhesive surface of the tubular material is capable to attach to an intima of the vein, where further
• the adhesive properties for the tubular material are created by protrusions extending from both surfaces of the tubular material, and after the removal of the inner part of the sheath and the control cable,
• through manual pressing force applied to the skin of the patient along the area of the treated vein, the inner adhesive surface of the tubular material is capable to attach with its own counter-surface, thus closing the vein within two-sidedly adhered area of the tubular material.
