Abstract: A stent for implantation in a body lumen for protecting from rupture a fibrous cap in order to treat vulnerable plaque. One embodiment of the stent achieves staged expansion through stronger and weaker circumferential regions, and includes optional anchors positioned at the circumferential transition between the stronger and weaker regions. During the first stage expansion, the weaker region expands moving the anchors laterally apart. The anchors straddle the fibrous cap and embed into the vessel wall. The second stage expansion of the stent exerts gentler stresses by the weaker region against the fibrous cap while the stronger region exerts greater stresses on the remainder of the vessel wall to open the vessel.
