Processing of laser cutting heart stent

Stent Laser Cutting

Nitinol is a wonder material for minimally invasive medical applications, with two very important physical properties. First of all it is super stretchy, flexible and kink resistant. This is an ideal material for guide wires and those that need to be traversed remotely through blood vessels and other small conduits in the body.

In medical implants, the design temperature will be slightly lower than the body temperature. For example, a finished stent or coronary valve prosthesis is presented in a folded form for insertion during non-surgical treatment. After the implant enters the human body or closes the catheter, it is heated by body temperature or warm water to completely restore it to its original shape.

How are nitinol stents made

Possibly for the orifice for medical analysis purposes, the internal roughness of the finish is within the winding tolerance of Ra0.008μm or less, and the mirror finish is processed, especially for medical device parts such as cardiac stents, catheters, vascular balloons, etc., which are finished in laser After processing, metal residues need to be removed, oxide film needs to be removed, final polishing needs to be carried out, metal materials that can be processed, Ni/Ti, βTi, SUS316L, SUS304
