Abstract:
A method for producing a steel component with a metallic anti-corrosion coating from a sheet steel product comprising at least 0.4% by weight Mn is disclosed. The sheet steel product is annealed in a continuous furnace under an annealing atmosphere containing up to 25% by volume H2, 0.1% to 10% by volume NH3, H2O, N2, and process-related impurities as the remainder, at a dew point between −50° C. and −5° C. at a temperature of 400 to 1100° C. for 5 to 600 s. The annealed sheet steel product has a 5 to 200 μm thick nitration layer with a particle size finer than the particle size of the inner core layer. Once coated with a metallic protective layer, a blank is separated from the annealed sheet steel product, heated to an austenitising temperature of 780 to 950° C., hot-formed, and cooled so that a hardened structure forms.

The present invention refers to medical devices comprising fluorinated polymers, especially to tubings, used for constructing catheters like balloon catheters, delivery catheters or guide catheters.
Abstract:
An improved apparatus for delivering and deployment of an expandable stent with a protection sheath within a blood vessel is provided. The system comprises a fluid pressure device which is coupled with a retraction device for the protection sheath such that after retraction of the protection sheath the stent is automatically deployed by the fluid pressure device. The advantage of the invention is an easy and simple operation of the apparatus.
