Key result
Modified thermoplastic polyurethanes demonstrate tunable mechanics and favorable biocompatibility for heart valve scaffolds.
Why the study?
Polycarbonate-based and polysiloxane-modified thermoplastic polyurethanes are promising for cardiovascular implants but require comparative evaluation of formulation, mechanical properties, and hemocompatibility.
This study establishes comparative formulation-property-hemocompatibility criteria for polyurethane heart valve scaffolds.
Supports preclinical development of tunable polyurethane scaffolds; leaves open clinical translation and long-term durability.
Polycarbonate-based and polysiloxane-modified thermoplastic polyurethanes (TPUs) are promising candidates for cardiovascular implants because of their tunable mechanical properties and favorable biocompatibility. In this study, we established comparative formulation–property–hemocompatibility criteria for...
