摘要： Apparatus and method for ablating target tissue including a non-linear area of tissue in the left atrium of a patient. The method can include selecting an ablation apparatus having an ablator with a tissue engagement section, penetrating a chest cavity of the patient, and identifying the target tissue. The method can also include positioning the ablation apparatus adjacent to the target tissue so that the tissue engagement section can transfer ablation energy to the target tissue. The method can further include energizing the tissue engagement section with ablation energy in order to create a footprint on the non-linear area of tissue in the left atrium and to reduce an overall mass of excitable tissue in the left atrium.

摘要： An electrosurgical instrument (12, fig. 1) including an elongated shaft (22) and a non-conductive handle (20) is disclosed. The shaft defines a proximal section (40), a distal section (42), and an internal lumen (50) extending from the proximal section. The distal section forms an electrically conductive tip (44) and defines at least one passage (52) for distributing fluid. Further, the shaft is adapted to be transitionable from a straight state to a first bent state (fig. 5). The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. With this in mind, an exterior surface of the shaft distal the handle and proximal the distal section is electrically nonconductive. In one preferred embodiment, the shaft is comprised of an elongated electrode body surrounded by an electrical insulator.

摘要： A system and method for creating lesions and assessing their completeness or transmurality. Assessment of transmurality of a lesion is accomplished by monitoring the depolarization signal amplitude in a local electrogram taken using electrodes located adjacent the tissue to be ablated. Following onset of application of ablation energy to heart tissue, the amplitude of a local electrogram measured with electrodes located adjacent tissue to be ablated first gradually drops and then stabilizes, indicating that the tissue being monitored has ceased making any contribution to the sensed electrogram. The amplitude drop and/or the following amplitude plateau may be used alone or together as indicators of transmurality. Detection of a rapid drop in amplitude may be employed as an indicator that the ablation process is proceeding too quickly and may be employed to trigger a reduction in the power of applied ablation energy. Detection of an insufficiently rapid drop in amplitude may be employed as an indicator that the ablation process is proceeding too slowly and may be employed to trigger an increase in the power of applied ablation energy.
