Abstract
An ablation catheter system and methods for repairing an annular organ structure comprising high frequency ablation for the purposes of tightening and stabilizing a tissue. A catheter suitable for high frequency ablation comprises a flexible tissue-contactor means located at the distal tip section of a catheter shaft for contacting an inner wall of the annular organ structure, and a needle electrode means located at or within the flexible tissue-contactor means for penetrating into the tissue, wherein the needle electrode means is deployable out of the tissue-contactor means in a manner essentially perpendicular to a longitudinal axis of the catheter shaft.
