Claim 0:
1. A method of making an expandable sheath, the method comprising:
forming a folded configuration in an elongated inner member by forming a crease along a first longitudinal edge and a second longitudinal edge of the elongated inner member so that a first circumferential portion is positioned at least partially between the first and second longitudinal edges in the folded configuration;
covering the elongated inner member with an elastomeric outer member; and
forming a proximal seal proximal a distal free end of the expandable sheath by extending a middle member from an outer surface of the elongated inner member to an inner surface of the elastomeric outer member, thereby blocking a flow path extending between the elongated inner member and the elastomeric outer member with the proximal seal and forming a distal portion of the flow path between the elongated inner member and the elastomeric outer member extending from the distal free end of the expandable sheath to the proximal seal;
wherein the distal portion of the flow path is in fluid communication with an opening between the elongated inner member and the elastomeric outer member at the distal free end of the expandable sheath.
