Method for treating and repairing mitral valve annulus
First Claim
1. A method for operating a system to tighten and stabilize a target zone of a collagenous tissue within a patient'"'"'s body, comprising the steps of:
- providing a device configured to deliver tissue-shrinkable energy to a target zone comprising an annular organ structure of a heart valve within a patient'"'"'s body via a catheter comprising a flexible tissue contactor member comprising energy-delivering elements, wherein said flexible tissue contactor member is configured to compressively confine an inner wall of said annular organ structure between a distal end of said flexible tissue contactor member and a proximal end of said flexible tissue contactor member, and wherein said flexible tissue contactor member is located at a distal tip of said catheter and inside at least one lumen of said catheter extending between said distal tip and a proximal end where said flexible tissue contactor member is deployed out of said at least one lumen;
introducing said catheter through to a site of said annulus;
deploying said flexible tissue-contactor member;
positioning said tissue-contactor member to compressively confine said inner wall of said annulus;
advancing said energy-delivering elements to contact tissue of said annulus; and
,delivering a tissue-shrinkable energy to said target zone wirelessly, wherein said tissue-shrinkable energy is provided noninvasively from outside a body of the patient, wherein said tissue-shrinkable energy is sufficient to shrink and tighten said annular organ structure.

Abstract
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.
