Abstract
An intravascular stent assembly for implantation in a body lumen, such as a coronary artery, is designed to treat a lesion with vulnerable plaque by reducing the fibrous cap stresses. A polymeric sleeve having first and second ends interconnects a first metallic stent and a second metallic stent. The first end is bonded to a distal end region of the first stent and the second end to a proximal end region of the second stent. The polymeric sleeve can be loaded with a therapeutic drug or agent to further control local thrombosis and/or induce healing if the plaque fibrous cap ruptures during or after implantation. Methods of making an intravascular stent assembly for the treatment of vulnerable plaque are also provided.
