Abstract
Apparatus and methods for stenting are provided comprising a self-expandable stent that is at least partially covered with a biocompatible material configured to prevent dynamic self-expansion of the stent. The biocompatible material is irreversibly expandable by suitable means, for example, a balloon. Thus, the apparatus may be tailored in-vivo to a vessel profile, in a manner similar to a balloon-expandable stent, but maintains the flexibility required for use in tortuous anatomy and in vessels that undergo temporary deformation, in a manner similar to a self-expandable stent. Apparatus is also provided for stenting at a vessel branching, and for localized delivery of therapeutic agents.
