PRESHAPED ABLATION CATHETER FOR ABLATING PULMONARY VEIN OSTIA WITHIN THE HEART |
摘要 |
Catheters and methods are provided for performing medical procedures. The catheter comprises an elongated flexible integrated catheter body having proximal and distal shaft portions, a central support positioned inside the distal shaft and at least one operative element carried by the distal shaft portion. The distal shaft portion has a proximal section configured to be internally actuated to form a simple curve with an apex that can be inserted into the vessel ostium, an intermediate section pre-shaped to form a curve that bends opposite the simple curve, and a distal section configured to be placed into a non-radial relationship with the vessel ostium when the apex of the simple curve is inserted into the vessel ostium. |
