Schematic comparing an obstructive colorectal cancer treated with self-expanding stent and a magnetically compressed tumor spheroid. (A) Tumor growth within the colorectal wall, occluding the lumen of the colon almost entirely (top). To avoid this obstruction, a self-expanding stent is inserted inside the colorectal lumen and extended to obtain a re-opening of the lumen, up to 75% of its initial radius (bottom). This results in anisotropic compression of the tumor. (B) Representation of a magnetically molded tumor spheroid (top) and its anisotropic compression upon magnet application (bottom).
