Abstract
An expandable delivery sheath is provided for intravascular introduction into a patient's vasculature by means of a guiding catheter. An interventional device, such as a stent delivery catheter, is subsequently advanced within the expandable sheath to a point where the stent traverses an arterial lesion. The sheath forms a protective barrier between the lesion and the stent and it delivery catheter, thereby preventing the creation of emboli which might otherwise be produced by abrasion of the stent against the plaque of the arterial lesion. Prior to expansion of the stent, the expandable sheath is retracted from the area of treatment.
