    摘要: An introducer assembly for accessing a target site in the anatomy of a patient includes a sheath having a proximal end and a distal end, and having a lumen extending therethrough. At least a portion of the sheath distal end has a curved configuration. A tapered dilator has a proximal end and a distal end, and is sized to be received in the sheath lumen. The dilator has a length such that at least a distal tip portion of the dilator extends beyond the distal end of the sheath when the dilator is received in the sheath lumen. The dilator may be formed of polyurethane, and has a stiffness not exceeding a stiffness of the sheath curved portion such that the sheath substantially maintains the curved configuration when the dilator is received in the sheath lumen.
