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.
摘要翻译：本发明的系统和方法测量身体组织与支撑在导管上的一个或多个电极之间的接触的量或质量。在另外的方面，本发明涉及用于响应于在消融过程期间从该电极或其它电极衍生的组织接触数据来控制对导管上的特定电极的功率输送的方法。本发明监测和处理关于在消融过程期间传送的脉冲射频能量的脉冲数的信息。组织接触的量或质量通过将在间隔期间递送到特定电极的脉冲数量与递送至多个电极中的至少一个其他电极的脉冲数量或在消融过程期间导出的数据进行比较来测量。该系统和方法可以提供各种电极之间的组织接触的规格的显示，并且还可以响应于组织接触的规格自动控制脉冲RF能量的分布。

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 at least one ablation electrode 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 an edge of an intracardiac orifice, for example, the tricuspid annulus whereby the at least one electrode engages a target tissue, for example, the isthmus of tissue between the tricospid annulus and the inferior vena cava, deflecting the distal tip into a hook-shaped configuration, and activating the at least one electrode to produce a substantially continuous lesion on the target tissue. The method makes use of a catheter pre shaped at its distal end, steerable with pull wires in two different normal planes, having one electrode which slides along the distal tip of the catheter.

摘要： A device, and method for performing cardiac ablations includes a therapeutic instrument, for example, an ablation catheter (10), to which is mounted a flexible, and braided electrode (14). The electrode configuration is selected so that it has a desired surface area for proper heat convection properties. RF energy (26) is delivered to the electrode to heat, thereby ablate local heart tissue, with the electrode having good convection abilities to protect against coagulation, embolisms, and other undesirable effects of ablation procedures.
