Abstract:
Apparatus and methods for stenting are provided comprising a stent attached to a porous biocompatible material that is permeable to endothelial cell ingrowth, but impermeable to release of emboli of predetermined size. Preferred stent designs are provided, as well as preferred manufacturing techniques. Apparatus and methods are also provided for use at a vessel branching. Moreover, embodiments of the present invention may comprise a coating configured for localized delivery of therapeutic agents. Embodiments of the present invention are expected to provide enhanced embolic protection, improved force distribution, and improved recrossability, while reducing a risk of restenosis and thrombus formation.
