Abstract
A stent for helping to hold open a lumen in a tubular body structure has at least one axial portion (preferably an axial end portion) that stents the surrounding portion of the tubular body structure to a lesser degree than another axial portion of the stent. For example, the stent portion that stents to a lesser degree may be circumferentially weaker than the other stent portion, or it may recoil more than the other stent portion after the stent is applied by being circumferentially expanded and then released.
