Abstract
A gradually self-expanding stent is provided with a first region of stent cells. A restraining material is attached to the first region and restrains the first region from expanding to the expanded configuration. Over time the restraining material releases the first region to allow the first region to expand to the expanded diameter. The first region is located longitudinally between two second regions. The second regions expand at a faster rate than the first region.
