Abstract
A sheath for advancement into a vessel of a patient having a stenosis therein which at least partially occludes the flow of blood in the vessel. A flexible elongate tubular member has proximal and distal extremities with a lumen extending from the proximal extremity to the distal extremity. A portion of the distal extremity of the flexible elongate tubular member is radially expandable. The expandable portion carries stiffening elements that impart pushability and column strength to the expandable portion.
