摘要： A deflection mechanism for selectively inducing a bend in a catheter body includes an elongated deflection wire extending within a deflection lumen of the catheter body and into a handle. A guide track is formed within the handle and a thumb wheel is mounted proximal to the elongated guide track within the handle and supports a pinion gear; the thumb wheel and the pinion gear are adapted to be rotated about a common thumb wheel axis, which extends substantially perpendicular to the longitudinal axis. A rack arm extends obliquely to the longitudinal axis of the handle and includes runners received by the guide track, an attachment point coupling the deflection wire to the rack arm and a linear rack engaging the pinion gear. Rotation of the thumb wheel in a first direction draws the deflection wire proximally through the deflection lumen.

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 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 local electrogram is measured with electrodes located adjacent tissue to be ablated so that the ablation energy to ablation elements can be selectively reduced or terminated when transmurality is detected.

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.
