A Computational Journey Toward an Optimal Design for Metamaterial Epicardial Passive Sleeves
Advanced Healthcare Materials, EarlyView.Passive epicardial sleeves are evaluated in 3D in‐silico heart models to reveal how sleeve geometry, stiffness, anisotropy, and metamaterial architecture influence cardiac mechanics after myocardial infarction. A continuum‐to‐auxetic design exploration shows that region‐specific mechanical engagement can reduce infarct bulging and modulate torsional ...
