摘要：
Devices and minimally invasive methods for reducing the size of a cardiacvalve annulus in a beating heart. Embodiments of the methods can includeadvancingan energy delivery catheter into the heart proximate a cardiac valve annulus,the energydelivery catheter having at least two electrodes. Then advancing the twoelectrodessuch that the two electrodes pierce into the cardiac valve annulus at adistance fromone another. The methods further include applying an approximating force to atleastone of the two electrodes, thereby reducing the distance between the twoelectrodes,and applying energy between the at least two electrodes, thereby heating andshrinkingthe annulus in a direction of the approximating force.
