Embodiments relate to systems and methods for magnetized stent having growth-promoting properties. A stent assembly comprising a tubular elongated body having a magnetized region and a tissue nidus area is inserted beneath the orifice of a vascular aneurysm. The magnetic region can serve to attract and position both residua! red biood cells and magnetically nano-ireated growth-promoting ceils to the orifice area of the aneurysm. The outer circumference of the tubular elongated body can act as a floor or scaffold for regenerated smooth vascular muscle cells. In embodiments, the tissue nidus area can be provided on the exterior stent, while the magnetized region is provided on the interior stent, of a stent-in-stent structure. In embodiments, the exterior stent is made of biodegradable material which gradually dissolves or dissipates in situ. |
