Abstract
System and method for repairing an annular organ structure of a heart valve, an annular organ structure of a venous valve, a valve leaflet, chordae tendinae, papillary muscles, a sphincter, and the like. May be deployed into the heart via a catheter percutaneously or via a cannula through a percutaneous intercostal penetration. Provides a tissue-shrinkable energy that may be applied to the target annular organ sufficient to treat the target organ structure. Reshaping collagen rich tissue through the emission or generation of heat or radiation within the tissue modifying the collagen through the process of denaturation. Provides tissue-shrinking energy to the valvular annulus of a beating heart without the interruption of blood flow through the valve.
