A delivery apparatus for introducing an implant, such as a vena cava filter, for capturing emboli in a body vessel. The apparatus includes an outer sheath having a tubular wall defining a lumen formed therethrough and having a proximal end extending to a distal end. The tubular wall includes an inner surface and may also include optional reinforcing members. A radiopaque marker band is disposed about the inner surface adjacent the distal end, and a tubular liner is disposed along the inner surface. The tubular liner comprises at least one of polyimide, PEEK, and PVDF. An inner catheter is slidably disposed within the lumen of the outer sheath and has a distal portion configured to engage and deliver the implant through the distal end of the outer sheath in the body vessel.
