Abstract
Methods and systems for improving the competency of a venous valve wherein one or more compressor(s) (e.g., space occupying material(s) or implantable device(s)) is/are delivered to one or more location(s) adjacent to a venous valve to compress the venous valve in a manner that causes one or both leaflets of the valve to move toward the other, thereby improving closure or coaptation of the valve leaflets. The compressor(s) may be delivered by an open surgical approach, by a direct percutaneous approach or by a transluminal catheter-based approach.
