    In this study, we investigate the dynamics of unsteady electro-osmotic pulsatile ow involving a hybrid nanouid within a curved artery, inuenced by both a stenosis and an embedded catheter. The hybrid nanouid, a mixture of silver (Ag) and aluminum oxide (Al2O3) nanoparticles dispersed in blood, is modeled via the Carreau non-Newtonian framework to more accurately represent the intricate nature of blood ow. The electro-osmotic forces introduced simulate the eect of an external electric eld, while the catheter serves as an additional structural constraint within the artery. To account for both the curvature of the vessel and the overlapping stenosis, we derive the governing equations for this model. Employing numerical methods, particularly the nite dierence approach, we solve the nonlinear partial dierential equations that govern the ow, temperature, and concentration distributions. Our ndings suggest that the hybrid nanouid demonstrates enhanced thermal and ow properties compared to standard uids. The results showed signicant inuences from electroosmotic forces, curvature, and pulsatility on velocity, temperature, and concentration proles. Furthermore, an increase in the electroosmotic and Weissenberg parameters substantially accelerated uid velocity by reducing viscous drag while improving mass transport. These results oer valuable insights into the behavior of blood ow in catheterized arteries and may inform future advancements in cardiovascular treatment technologies.
