    摘要： An electrophysiology catheter introduced through the groin and inferior vena cava into the right side of the heart comprises an elongate flexible shaft having a steerable distal section and a prolapsing section located proximally of the distal section. The distal section is inserted into the coronary sinus and a back-steering force is applied to the catheter to anchor the distal section therein, after which the catheter is further advanced to prolapse the prolapsing section against the high right atrium. Electrical pathways in both the coronary sinus and the high right atrium are mapped using respective electrode pairs carried on the distal and prolapsing sections of the catheter.

    摘要： Catheters, systems, 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 catheter body, which includes a proximal shaft portion and a distal shaft portion, and a tracking element carried by the distal shaft portion. The proximal section is pre-shaped to form a curve having an apex sized to be inserted into the vessel ostium, and a distal section configured to contact the adjacent tissue when the curve apex is inserted within the vessel ostium. The method may comprise inserting the curve apex into the vessel ostium to place the distal section in contact with a first tissue site adjacent the vessel ostium, and determining a location of the tracking element(s) within a coordinate system while the distal section is in contact with the first tissue site.

    摘要： Steerable catheter that has fluid transfer capability is provided. The catheter includes an elongate flexible shaft having a proximal end and a distal end, an operative element carried at the distal end of the shaft, and a medium conveying conduit carried within the elongate shaft, the conduit having a distal end that is affixed relative to the distal end of the elongate shaft, and a proximal end that is configured to move relative to the proximal end of the shaft. In this manner, the proximal end of the medium conveying conduit is allowed to slide relative to the proximal end of the shaft as the distal end of the shaft changes shape, thereby preventing kinking of the conduit.

    摘要： A flexible, steerable intravascular catheter includes an elongate flexible shaft having a heterogeneous or multi-zone stiffness profile or structure. A first or distal portion of the catheter shaft may have a substantially constant or distinct stiffness or flexibility, a second, intermediate or transition section is proximal relative to, and less flexible than, the first section, and a third section is proximal relative to, and also less more flexible than, the first section. The third section also includes a substantially constant or distinct stiffness or flexibility. The flexibility or stiffness of the second section varies along its length, e.g., in a substantially linear, step-like or ramp-like manner to provide a smooth or gradual transition between the stiffness of the first or distal section and the flexibility or stiffness of the third or proximal section.
