    Abstract: The catheter is arranged at the distal end with a suction opening and a dormia basket type extension. The extension is comprised of a highly elastic material, so that high pressure liquid can be injected through very narrow nozzles. The arteries or veins can be subjected to the pressure or a laser can be applied. The nozzle jet is respectively aligned on a funnel suction opening of the catheter. The branches of the dormia basket are assembled together in a ball at the tip so that the vessel wall is not traumatised. A central opening in the ball enables the catheter to be used across a thin guide wire.

    Abstract: The blood vessel support comprises a base element made from a spiral shaped tubular lattice. The base element has a series of occasional transverse ties fixed to it at intervals to act as stabilisers. The ties are positioned to ensure maximum longitudinal flexibility is achieved whilst lateral stability is maintained. The structure can also be provided with connections running in the longitudinal direction. The support may be implanted into the vessel in the compressed state and may expand in-situ to its functional diameter. The implant can be covered with a plastic skin and be coated with a medication.
