Abstract
An intravascular stent having a stent body and at least one cover overlying the stent body to cover the first portion of the stent body. The cover has a first region attached to the stent body and a second region unattached to the stent body. Multiple covers can be attached to the stent body in overlapping arrangement, each cover having a free unattached end. The free ends reduce the overall stiffness of the stent.
