PNIPU: 3D printing of cardiovascular stents

2024: Product Launch

In August 2024, it became known about the launch of a new technology for 3D printing of cardiovascular stents from biodegradable materials in Russia. This innovation was developed by scientists at Perm Polytechnic University (PNIPU), creating personalized coronary stents from biocompatible polymers. The technology includes not only the design, but also the manufacture of stents using 3D printing, which opens up new opportunities in cardiac surgery and medical practice.

The development of stents from poly-l-lactic acid, a biodegradable material, is a breakthrough in medical technology. This polymer is able to degrade in the body to non-toxic products that are naturally excreted. This technology is being developed within the framework of the federal project "Platform of University Technological Entrepreneurship," where the research group of the Perm Polytechnic became one of the winners of the "Student Startup" competition.

The technology developed in the PNIPU biofluidities laboratory is based on the design, calculations and 3D printing of stents, which can be customized for each patient. The research aims to study the mechanical properties of prostheses, as well as the mathematical modeling of their behavior in the human vascular system to choose the most suitable design for various clinical cases. Particular attention is paid to the radial stiffness of stents, which is a key parameter for the efficiency of the structure.

One important area of use of new stents is cardiovascular surgery in children with congenital heart disease. In these cases, short-term or medium-term stenting is required without the need for subsequent surgical removal of the structure. The development of biodegradable stents helps overcome the limitations associated with metal analogs, which can cause long-term complications or require repeated operations.^[1]
