3D-Printed Surgery Stents for Easy Closure of Arteries

A new 3D printed stent is developed by the Scientists at the University of Nebraska-Lincoln, which can help the cardiologists in suturing the small arteries. It is 3D-printed with a sugar-based substance, which melts and dissolves in minutes subsequent to the closure of the artery.

Currently, one of the major challenges faced by the specialist is joining the open end of arteries. Nevertheless, the technique is dynamic in a range of surgical procedure, such as transplantation of organ or reconstructive surgeries. It is well-known that plastic surgery is time-consuming and highly skill-dependent.

These researchers developed a simple tool to support specialists to complete this critical procedure. The resorbable 3D-printed stent which can significantly make things easier and speed up the procedure. This simple idea will help surgeon to insert the tiny tube-like structure into both ends of the open artery, and sticks to the inner surface of the vessel, to hold arteries together during the suturing process. Nevertheless, the device is totally dissolves in over a minute after the arteries are sealed.

A sucrose based materials was used to accomplish these specific properties such as dissolving in bloodstream and reducing the formation of blood clots. As the 3D printing technique was used for the production of the device, it is possible to produce the stents in range of sizes to fit arteries of different people.

Till now the device has been in the pre-clinical studies, which reduced the total suturing time with perfect closure of the arteries. Sooner or later, such stents are expected to be custom printed for various patients around the world.
