The present work is dedicated to the design and manufacturing of stents by means of laser milling.

The key issue was the improvement of the usability of stents with the following approaches: to increase width and to decrease thickness of stent walls in order to lower the pressure on the walls of blood vessels; - to deposit metal coatings on stent walls to increase corrosion resistance of stents and  to increase the area of “useful” surface of stents by forming  extra grooves (“pockets”) that could be used for drugs application on stent walls making  stent active surface in terms of drug delivery.

Technological processes of stent manufacturing were verified experimentally. We used medical needle (wall thickness – 200 microns, inner diameter – 0,8 mm). As a result, 2 mm long stents with wall thickness ranging from 80 microns to 200 microns were manufactured. These stents were implanted into the body of laboratory rat and were inflated to ensure normal blood flow.

Inner protection screen was used (copper rod that was placed inside the tube workpiece and noticed that there was a transfer of screen material (Ti and Cu) on the inner walls of stent.
