    摘要： A method of performing a medical procedure, such as surgery, is provided. A nerve is stimulated in order to adjust a beating of the heart to a first condition, such as a stopped or slowed condition. The medical procedure is performed on the heart or another organ. The stimulation of the nerve is stopped in order to adjust the beating of the heart to a second condition, such as a beating condition. The heart itself may also be stimulated to a beating condition, such as by pacing. The stimulation of the nerve may be continued in order to allow the medical procedure to be continued. A sensor to sense a characteristic of a fluid or tissue, such as an impending contraction, may be also used during the medical procedure. Systems and devices for performing the medical procedure are also provided.

    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 method and system for ablating tissue to provide a desired set of lesions. The system includes an ablation apparatus having an elongated shapeable section carrying a mechanism such as an electrode for applying ablation energy along the shapeable section. The shapeable section includes a member of shape memory material having a memorized configuration. The shapeable section is shaped manually or using fixtures to display a configuration corresponding to one of the desired lesions and is then employed to create the desired lesion. Thereafter the shapeable section is heated to cause it to resume its memorized configuration. Shaping, heating and ablating to create lesions are continued as necessary provide the desired set of lesions. In some embodiments of the invention, heating may be accomplished using heating elements built into the shapeable section.
