Surgical Valve Replacement is the standard of care for patients with severe aortic valve calcification. Valve calcification is common with aging but patients are often refused surgery due to comorbidities. Minimally invasive valve replacements are available and have demonstrated applicability to patients not qualified for open heart surgery. The goal is to design a self-expanding Nitinol stent with features to enable attachment to a polyurethane valve, facilitate deployment and repositioning within the aortic annulus. The design was performed in collaboration with Nitinol stent manufacturers, private consultants, and surgeons. The most promising stent designs were ordered to be custom manufactured and the valve was attached to the stent for deployment and bench-top performance testing.
