Abstract
An expandable introducer sheath for use in inserting a medical device into a body vessel of a patient includes a body which extends from a proximal end to a distal end along an axis. The body includes an inner layer, an outer layer, and an expandable reinforcement member which is disposed between said inner and outer layers. The expandable reinforcement member is configured to radially expand as the medical device is axially advanced or retracted through said introducer sheath. Once the medical device has exited the introducer sheath, the expandable reinforcement member facilitates a return of the introducer sheath to its original or unexpanded condition.
