A ureteral access sheath having nonuniform axial-stiffness adapted for proximal pushability needed for placement while also having distal flexibility to minimize trauma to the body lumen and ureter. Embodiments in accordance with the present invention provide a nonuniform axial-stiffness ureteral access sheath comprising a nonuniform axial-stiffness jacket encapsulating the reinforcement layer with the inner liner. Other embodiments in accordance with the present invention provide a nonuniform axial-stiffness ureteral access sheath comprising a nonuniform axial-stiffness reinforcement layer encapsulated between a single axial-stiffness jacket and the inner liner. Other embodiments in accordance with the present invention provide a nonuniform axial-stiffness ureteral access sheath comprising a nonuniform axial-stiffness jacket encapsulating a nonuniform axial-stiffness reinforcement layer with the inner liner.
