    Abstract: 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.

    Abstract: A catheter with ablation and potential sensing capabilities is adapted for outer circumferential contact with an opening of a tubular region and inner circumferential contact within the tubular region. The catheter has a proximal electrode assembly and a distal electrode assembly for ablation of an ostium and potential sensing inside the pulmonary vein so that it is possible to obtain ECG signals inside a pulmonary vein when ablating around the ostium. The distal electrode assembly has an elongated member defining a longitudinal axis and a plurality of spines surrounding the member and converging at their proximal and distal ends, where each spine has at least one electrode and a curvature so that the spine bows radially outwardly from the member. The proximal electrode assembly has a proximal electrode assembly has an elongated member configured with a generally radial portion and a generally circular portion generally transverse to the catheter axis, where the generally circular portion comprising a plurality of electrodes. The control handle advantageously allows a user to manipulate a tensile member for changing the curvature of the spine.

    Abstract: 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.
