Zusammenfassung:System and method for repairing an annular organ structure such as heart valve including valve leaflet, chordae tendinae, papillary muscles and the like. Provides a deployable structure in the form of a plurality of tissue-contactor members with integrated tissue-shrinkable energy-emitting elements. Said plurality of tissue-contactor members in a deployed state having a configuration of radially expanded middle region suitable for contacting the inner wall of an annular organ structure for effectively applying tissue-shrinkable energy site-specifically. May be deployed into the heart using a minimally invasive surgical procedure. Reshaping collagen-rich tissue through the emission or generation of heat or radiation, modifying the tissue through the process of denaturation. Configuration of deployable structures at distal section of system enables method of treatment of an annular organ structure without an interruption of flow of blood or bodily fluid through the valvular annulus.
