Abstract

A delivery device for delivering a stent device that is expandable from a radially reduced, delivery configuration to a radially expanded, deployed configuration. A retaining sheath is disposed over the stent device for maintaining the stent device in the delivery configuration. A pull line to be pulled upon is provided to retract the retaining sheath in a rolling manner such that the retaining sheath is folded back on itself to provide a radially inner sheath of the retaining sheath, a radially outer sheath of the retaining sheath and a fold portion therebetween. The retaining sheath may be made of a cold drawn plastic at least along the path of travel of the fold portion in retracting the retaining sheath from over the stent device.
