    摘要: Systems and methods deploy an electrode from a catheter assembly. The systems and methods provide a catheter handle having a trigger lever adapted to carry an actuator rod. The actuator rod is adapted to cause movement of the electrode between a retracted position and an extended position. A pinion is carried by the trigger lever for engagement with a rack carried by the actuator rod. Compression of the trigger lever moves the rack along the actuator rod between a first position corresponding to the electrodes being in the retracted position and a second position corresponding to either the primed electrode firing position or the electrodes being in an extended position.

    摘要: A method of forming a composite lesion pattern in a tissue region at or near a sphincter comprising providing a catheter having a plurality of energy delivery devices coupled to the catheter. The catheter is introduced at least partially into the sphincter. Energy is delivered from the energy delivery devices to produce the composite lesion pattern. The composite lesion pattern comprises a radial distribution of lesions about the tissue region and a longitudinal distribution of lesions along the tissue region.
