Stent connector omission may optimize hemodynamics in models; animal-level computational data leave open any clinical impact on restenosis.
Computational fluid dynamics demonstrate that stent design, specifically larger interstrut spacing and absence of longitudinal connectors, improves wall shear stress restoration, potentially reducing restenosis risk.
He et al. (2005) studied Restenosis after stent implantation. Stent design patterns vs. Alternative stent configurations was evaluated on Wall shear stress (WSS) and flow characteristics. Computational fluid dynamics modeling showed that stent designs without longitudinal connectors had up to 11% larger restoration in wall shear stress compared to those with connectors.
