ABSTRACT:
An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for rupturing a fibrous cap to controllably release vulnerable plaque. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by links. The stent includes struts and links of varying strengths about the circumference of the stent. The weaker struts and links require less force to open and, hence, may apply more stress to rupture the fibrous cap while the stronger struts and links protect the healthy portions of the body lumen. In another embodiment, the stent may include stress concentrators positioned on outer surfaces of the links. The stress concentrators are aligned with the fibrous cap prior to stent expansion so that upon stent expansion, the stress concentrators induce stress to rupture the fibrous cap, thereby releasing the vulnerable plaque.
