An implantable medical device having enhanced endothelial migration features, generally comprises: a structural member including cross-section having a leading edge and a trailing edge interconnected by a third surface region, the leading edge including a second surface region in a generally curvilinear cross-section, and the trailing edge including a fourth surface region in a generally curvilinear cross-section, whereby fluid flow over the second surface region generate shear stress at the second surface region without an eddy region in the second surface region.
