Manufacture of stents, stent grafts and other vascular prostheses, surgical transplants

The manufacture of stents, stent grafts and other vascular prostheses involves the development and production of implants to treat vascular diseases such as aneurysms and stenoses. Current industry trends show an increasing integration of minimally invasive techniques and the use of bioresorbable materials that break down in the body after fulfilling their function. Companies face challenges such as complying with strict regulatory requirements and ensuring the highest quality standards in production. Innovations in materials science and manufacturing technologies are helping to increase patient safety and improve the effectiveness of treatments.

The KERN ABT analytical balance is essential for checking the stent base bodies both after electropolishing and before final assembly. After electropolishing, the loss of mass is measured in order to make statements about the smoothing and rounding of the stents. Before final assembly, the balance enables an intermediate check in which stents that are too large or too small are sorted out to ensure that only products of the highest quality are processed further.
