    摘要： A cardiac arrhythmia ablation catheter that has a highly flexible tubular distal segment particularly adapted for navigating and exploring a ventridular cardiac chamber forming a lumen through its length which connects to a distal electrode-carrying tip which is provided with an independently rotatable tip electrode mounted at the distal end tip of the distal tip section and adapted to engage and roll over the internal surface of a ventricular heart chamber of interest without rotation of the catheter itself. A wire deflection control system is provided to deflect the distal tip system of the distal catheter section in a controlled manner and a hand-operated control is provided to control the rotation of the rotatable tip electrode.

    摘要： Catheters and methods are provided for performing medical procedures, such as tissue ablation, adjacent the ostia of anatomical vessels, such as pulmonary veins. The catheter comprises an elongated flexible integrated catheter body having proximal and distal shaft portions 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 (e.g., using a steering mechanism or pre-shaping the proximal section) 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 (tangential or oblique) with the vessel ostium when the apex of the simple curve is inserted into the vessel ostium. By this arrangement, the operative element is configured to be placed firmly in contact with tissue at a predefined radial location relative to the vessel ostium when the apex of the simple curve is inserted into the vessel ostium.
