Abstract
An expandable dilator for use with an expandable sheath includes a shaft having a tapered distal tip, a body, a proximal end, and a lumen extending longitudinally from the distal tip to the proximal end. The expandable dilator includes an expansion mechanism extending radially outward from the outer surface of the shaft. When the expandable dilator is withdrawn proximally into the expandable sheath, the expansion mechanism engages the distal end of the sheath and expands the sheath as the expansion mechanism moves proximally through the sheath.
