Abstract:
1. A method for stenting a vascular system comprising: providing an apparatus comprising a stent and a material disposed about the stent, the stent having proximal and distal ends, and a lumen extending therebetween, the material having a multiplicity of pores selectively arranged along a length of the stent, at least some of the pores having a minimum width to enable endothelial cell ingrowth and a maximum width to prevent release of emboli larger than a predetermined size, at least some the pores allowing continued blood flow therethrough; advancing the apparatus in a collapsed delivery configuration to a treatment site within a vascular system; deploying the apparatus to an expanded configuration to engage a wall of the vascular system at the treatment site; and enabling the endothelial cell ingrowth through the pores permeable to endothelial cell ingrowth to cover at least a portion of an interior surface of the stent while retaining the emboli larger than the predetermined size against the wall of the vascular system.
