Abstract
A radially expandable intravascular medical device is disclosed. The device typically includes two members. The first member is an outer tube-shaped sheath which is radially expandable by being formed from elastic material or other means and having relatively low column strength. The second member is an inner portion extending throughout the outer tube. This inner portion includes a slit to allow it to expand radially as well. Using the structure diagnostic, therapeutic, or other desired objects may be conveyed through the device yet still enable the device to have a smaller cross-sectional area throughout most of its length than the object conveyed therethrough.
