Our client’s desire was to obtain micro reservoirs on the surface of cardiac stents. Volume control and positioning precision were critical. We started by producing prototypes and ended with a technology transfer with the industrialization of our process.
Technically one stent host 2920 micro reservoirs of a diameter of 70 µm for a total volume of 250 nL. Each cavity has to be precisely positioned at the center of the stent strut.
