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.

Method for treating and repairing mitral valve annulus

A surgical probe and methods for targeted treatment of structures of the heart with heat and radiofrequency energy. The probe which is designed to operated by hand has a elongate member with a handle and an energy-delivering member in an adjustable loop configuration. The control placed on the handle allow the user to alter the length of the loop configuration of the energy-delivering member and to thus place energy-delivering elements located on the energy-delivering member at selected or targeted portions of the heart or structures within the heart. The elongate member is conformable and can be bent into different configurations to allow additional targeted treatment of the particular portions of the heart.

Surgical probe and methods for targeted treatment of heart structures

A catheter system and methods for repairing a valvular annulus or 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.

Methods for treating and repairing mitral valve annulus

A catheter system and methods for repairing a valvular annulus or an annular organ structure of a patient comprising sandwiching and compressing the annulus and applying heat sufficient to shrink or tighten tissue surrounding the annulus defect.
