The current article is concerned with the shape impact of Ag-nanoparticles on the peristaltic flow through curved annulus having convective heated walls. Endoscopy is the medical device which is inserted in the body for the surgical execution to treat diseases. The gold nanoparticles are incorporated with peculiar shapes namely, platelets, cylinders and bricks. In the curved tube, the nature of Ag/blood medicated is formulated in toroidal coordinate system. The ratio of half tube-width to wavelength is tiny enough to maintain the uniform pressure over the cross-section. A perturbation technique is used to solve the formulated equations for an axial velocity and energy. The plots for explicit values of the embedded parameters such as the Biot number, endoscope radius, the amplitude ratio and the volume fraction are presented. One important finding of the present study is that the velocity increases near the inner wall of endoscope while it declines close to the outer tube wall. A notable difference is observed between the flows through non-curvature and curvature annulus from the obtained results. The curvature parameter enhances the velocity for the curvature tube more significantly.a#13; a#13;
