    摘要: Methods and apparatus for delivering precise amounts of fluid under pressure into cardiac tissue for the purpose of facilitating ablation of the tissue along a desired lesion line. One method injects fluid under pressure through a discharge orifice in a needle-less injection device. The injected fluid can be a cytotoxic fluid and/or a highly conductive fluid injected in conjunction with radio frequency ablation to create an ablative virtual electrode. The injected fluid can provide deeper and narrower conduction paths and resulting lesions. Radio frequency ablation can be performed at the same time as the fluid injection, using the injection device as an electrode, or subsequent to the fluid injection, using a separate device. In some methods, the injected fluid is a protective fluid, injected to protect tissue adjacent to the desired lesion line. Fluid delivery can be endocardial, epicardial, and epicardial on a beating heart. The present methods find one use in performing maze procedures to treat atrial fibrillation.

    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 impedance of the tissue to be ablated. Rather than attempting to detect a desired drop or a desired increase impedance, completeness of a lesion is detected in response to the measured impedance remaining at a stable level for a desired period of time, referred to as an impedance plateau. The mechanism for determining transmurality of lesions adjacent individual electrodes or pairs may be used to deactivate individual electrodes or electrode pairs, when the lesions in tissue adjacent these individual electrodes or electrode pairs are complete, to create an essentially uniform lesion along the line of electrodes or electrode pairs, regardless of differences in tissue thickness adjacent the individual electrodes or electrode pairs. Complete or partial submersion in a fluid of the ablating portion of the ablation device may be detected prior to, during or following an ablation procedure.

    摘要: A system, method and apparatus for regulating vacuum applied to surgical suction devices allowing the use of a single vacuum regulator and associated canister to provide vacuum to two suction devices, such as a suction stabilizer and a suction retractor. Vacuum controllers may be placed in the vacuum lines provided to each of two or more suction devices, or may be placed only in the vacuum line of the suction device believed most likely to detach during the procedure. Each vacuum controller is provided with a primary vacuum line, coupling its associated suction device to the output of the vacuum regulator and a pilot passage, also coupling the suction device to the vacuum regulator. The controller closes a valve in the main vacuum line in response to loss of vacuum attachment, which valve remains closed until attachment is reestablished. Closure of the valve results in substantial or complete blockage of the main vacuum line. The pilot passage, which may be part of the valve or a separate vacuum line, serves to allow reestablishment of vacuum attachment while the valve is closed. The pilot passage is configured so that airflow through the pilot passage is low enough that the other suction device or devices coupled to the vacuum regulator can still maintain vacuum attachment.
