Governing Equations and Boundary Conditions for Local Fluid Mechanics and Drug Transport within the Drug Laden Coating (c), Arterial Tissue (t), Lumenal Blood (b), and Peristrut Thrombus (th). Tissue, blood, thrombus, and coating domains are ΩTissue, ΩBlood, ΩThrombus, ΩCoat. Radial and axial axes, and time are r, z, t. Thickness of arterial tissue and coating are WTissue, LCoat. Arterial lumen radius and diameter are R, 2R. Lengths of vessel upstream and downstream from the strut are LProximal, LDistal. Duration of drug release is trelease. Maximum centerline velocity of blood flow is VC. Radial and axial component velocities are vr, vz. Dynamic pressure is P. Blood properties: dynamic viscosity and density are μ, ρ. Drug concentrations within tissue, blood, thrombus, and coating are Ct, Cb, Cth, Cc. Drug diffusivities within tissue, blood, thrombus and coating are Dt, Db, Dth, Dc.
