Abstract

Devices, systems and methods support tissue in a body organ for the purpose of restoring or maintaining native function of the organ. The devices, systems, and methods do not require invasive, open surgical approaches to be implemented, but, instead, lend themselves to catheter-based, intra-vascular and/or percutaneous techniques.
