Conventional heart stents are straight and typically chosen by the surgeon from a set of standard sizes. Recent research has shown the benefits of curved stents [Tomita et al. 2015]. Our method can be used to create freeform curved heart stents that can be adapted to the specific geometry of the patients’ blood vessels. Top row shows a zoom on the target vessel region and its 3D model reconstruction to approximate with our programmable auxetics. The stent is administered with a catheter to the correct position (bottom left) and inflated to its target geometry (bottom middle, right).
