Abstract: Example systems, methods, and apparatus are disclosed herein for a design and fabrication of patient-specific stimuli-responsive cardiovascular stents for coronary artery spasm treatment to eliminate post-surgical interventions. The stimuli-responsive material may be a magnetically-induced shape memory nanoparticle such as Hematite dispersed in PLA. Such Hematite may be at a concentration of 10 wt % to 20 wt %.

Abstract: Example systems, methods, and apparatus are disclosed herein for functional polymer nanocomposites for stimuli-responsive Dynamic Ring to treat Cardiac Mitral Valve Disorder. The stimuli-responsive material may be a magnetically-induced shape memory nanoparticle such as Hematite dispersed in PLA. Such Hematite may be at a concentration of 10 wt % to 20 wt %. The Dynamic Ring may be produced by a process of additive manufacturing including the polymer nanocomposites in the vicinity of the patient.
