Anti-coagulation stainless steel coronary arterial bracket and uses thereof

The invention relates to a medical apparatus, in particular to an anticoagulant stainless steel coronary support which is made from a high-nitrogen nickel-free austenitic stainless steel material with good blood compatibility. The support is of tubular structure with a mesh surface which is formed by orderly arranging a unit figure on the side surface of a tube along the circumference and axial direction, the primary supporting function is provided by U-shaped corrugated mesh wires extending along the axial direction, the corrugated mesh wires are connected into a whole body by soft mesh wires arranged at intervals, and the diameter of the mesh wire (width or thickness) is 40-100mum; and the surface of the support is passivated and coated with a medication. The anticoagulant stainless steel support has the advantages of good mechanical properties, good flexibility and good anticoagulant property, and can be used as a support for cardiovascular and cerebrovascular systems or a support for other cavity bodies.
