Specialists from Perm National Research Polytechnic University (PNRPU) have developed a method for 3D printing coronary stents, which are used in the treatment of coronary heart disease. The new method will improve their reliability and reduce manufacturing time. This was reported by the university's press service.
Coronary stents are metal frame structures used to restore blood flow in a vessel narrowed in a specific location. In the last ten years, these stents have been manufactured using laser cutting. PNRPU scientists have proposed a new approach that includes a two-stage printing technology for cobalt-chromium stents, ensuring the creation of more durable and reliable models, as well as accelerating their production process.
The developed methodology allows for the creation of personalized stents with a complex structure, which significantly improves their characteristics. An important feature of the new approach is the clear modeling and optimization of printing parameters, which allows for the manufacture of implants based on an individual patient's 3D model. This, in turn, helps to improve the condition of patients and increase the effectiveness of treatment for coronary heart disease.
