| abstract |
The present invention introduces a material, i.e. a device, which is insertable into a vein of a patient for treating e.g. chronic venous insufficiency. The device comprises inner (11, 24) and outer (12, 23) parts of a sheath, two-sidedly adhesive tubular material (22) with a supporting material (42) and protrusions (41), either a balong (21) or an inner protective film (33), and a control cable (14) for the insertion and extraction of the device along the vein. The supporting material may be compressed initially, and after removal of the outer part of the sheath, the supporting material with protrusions will expand towards the vein walls. After removal of the inner part of the sheath and the control cable, the treated vein area can be manually pressed on top of the skin, thus closing the vein through inner and outer adherence of the material. The protrusions may have a barbed shape. |
