    摘要: Systems and methods support arrays of multiple electrodes in asymmetric pattern, either radially, or axially, or both. Radial asymmetry makes it possible provide localized density of electrodes. Axial asymmetry makes it possible to locate electrodes in a pattern that closely conforms to the irregular contours of an interior body cavity, like the heart. In a preferred embodiment, the systems and methods operate the multiple electrode arrays to form continuous lesion patterns.

    摘要: Methods for using a surgical device integrating a suction mechanism with a coagulation mechanism for improving lesion creation capabilities. The device comprises an elongate member having an insulative covering attached about means for coagulating soft tissue with at least one diagnostic element coupled to an energy transfer element of the device. Openings through the covering expose regions of the coagulation-causing elements and are coupled to lumens in the elongate member which are routed to a vacuum source and a fluid source to passively transport fluid along the contacted soft tissue surface in order to push the maximum temperature deeper into tissue.
