A catheter system for repairing an annular organ structure of a patient, comprising: intimately contacting the annular organ structure by a tissue-contactor member having energy-delivering elements; and delivering tissue-shrinkable energy at the annular organ structure through the elements, wherein the tissue-shrinkable energy is applied at a distance wirelessly from the elements sufficient to shrink and tighten the organ structure. Tissue-shrinkable energy is infrared energy, ultrasound energy, focused ultrasound energy, ultrasound energy, radiofrequency energy, microwave energy, electromagnetic energy, laser energy, or a combination thereof.
