    摘要： Catheters for mapping and/or ablation are disclosed. In one embodiment, the catheter comprises a handle, a flexible shaft, a tip assembly, and a cable. The handle includes an actuator and is attached, at its distal end, to the proximal end of the flexible shaft. The flexible shaft has a longitudinal axis that extends along a length of the shaft. The proximal end of the tip assembly is attached to the distal end of the shaft and includes a fixed bend of approximatley ninety degrees relative to the longitudinal axis of the shaft. The distal end of the tip assembly includes an arcuate curve having a diameter. The arcuate curve is oriented in a plane that is approximatley perpendicular to the longitudinal axis of the shaft. The cable is attached to the actuator and the distal end of the tip assembly, and extends through the shaft. The cable is adapted to change the diameter of the arcuate curve in response to movement of the actuator.

    摘要： An apparatus for mapping and/or ablating tissue includes a braided conductive member that may be inverted to provide a ring-shaped surface. When a distal tip of the braided conductive member is retracted within the braided conductive member, the lack of protrusion allows the ring-shaped surface to contact a tissue wall such as a cardiac wall. In an undeployed configuration, the braided conductive member is longitudinally extended, and in a deployed configuration, the distal end of the braided conductive member is retracted to invert the braided conductive member.

    摘要： A novel device and method for performing cardiac ablations includes a therapeutic instrument, for example, an ablation catheter, to which is mounted a flexible, braided electrode. The electrode configuration is selected so that it has a desired surface area for proper heat convection properties. RF energy is delivered to the electrode to heat and thereby ablate local heart tissue, with the electrode having good convection abilities to protect against coagulation, embolisms, and other undesirable effects of ablation procedures.

    摘要： A method of treating cardiac arrhythmia, including guiding a distal end portion of a catheter, the distal end portion having a distal tip and accommodating an elongated configuration of ablation electrodes into a desired intracardiac region, for example, from the inferior vena cava into the right atrium of a human heart, and then from the right atrium into the right ventricle of the heart, pulling the catheter backwards, for example, towards the inferior vena cava, until the distal tip engages a edge of an intracardiac orifice, for example, the tricuspid annulus whereby the configuration of electrodes engages a target tissue, for example, the isthmus of tissue between the tricuspid annulus and the inferior vena cava, deflecting the distal tip into a hook-shaped configuration, and activating the configuration of electrodes to produce a substantially continuous lesion on the target tissue.

    摘要： The system and methods of the invention gauge the amount or quality of the contact between body tissue and one or more electrodes supported on a catheter. In further aspects, the invention concerns methods for controlling power delivery to particular electrodes on a catheter in response to tissue contact data derived from that electrode or other electrodes during the ablation procedure. The invention monitors and processes information concerning the number of pulses of pulsed radio-frequency energy that are delivered during an ablation procedure. The amount or quality of tissue contact is gauged by comparing the number of pulses delivered to a particular electrode during the interval to either the number of pulses delivered to at least one other electrode of the plural electrodes or data derived during the ablation procedure. The system and method can provide a display of the gauge of tissue contact among the various electrodes and also can automatically control distribution of pulsed RF energy in response to the gauge of tissue contact.
