摘要： A catheter configured to guide and support a balloon catheter for use in and around a pulmonary vein and its ostium, has an elongated shaft and a distal assembly, the elongated shaft including a proximal portion with a first flexibility and a distal portion including a second flexibility greater than the first flexibility, the distal assembly including an elbow portion and a generally circular portion generally transverse to the longitudinal axis, the generally circular portion including a third flexibility greater than the second flexibility. Single axis location sensors and sensing ring electrodes are carried on the generally circular portion.

摘要： A catheter has an electrode assembly adapted for use on an ostium and a stabilizing assembly movable between a stowed position within the catheter and a deployed position in the tubular region of the ostium. The stabilizing assembly has a balloon member that can be extended distally into the tubular region and inflated to wedge itself in the tubular region for anchoring the electrode assembly. The balloon member is mounted on an elongated extender that extends through the catheter and is provided with longitudinal movement to advance and withdraw the balloon between the stowed and deployed positions.
