摘要： An apparatus includes a shaft and an end effector at a distal end of the shaft. The end effector has a distal end and a proximal end with a longitudinal intermediate point between the distal and proximal ends. The end effector is sized to fit in an anatomical passageway within a cardiovascular system. The end effector includes at least one sensor electrode and a reference electrode. The at least one sensor electrode is configured to contact cardiovascular tissue and thereby pick up potentials. The reference electrode is configured to pick up a potential from fluid in contact with the reference electrode. The reference electrode is located proximal to the longitudinal intermediate point of the end effector. The end effector is configured to prevent the reference electrode from contacting tissue.

摘要： The disclosed technology includes a method of ablating tissue including positioning an electrode into contact with tissue and applying a first ablation signal to the tissue. The method can include forming a first lesion comprising a first depth with little or no first temperature change in a temperature of the tissue. The method can include applying a second ablation signal to the tissue different from the first ablation signal. Applying the second ablation signal to the tissue can include forming a second lesion comprising a second depth and generating a second temperature change in the tissue different from the first temperature change by at least 10°C. The method can include forming a combined lesion comprising the first lesion and the second lesion and comprising a combined size. The combined depth can be about 20% to about 40% greater than either of the first depth and the second size.

摘要： An apparatus for medical treatment includes a probe including multiple electrodes and configured to be inserted in a body cavity of a patient so as to bring the multiple electrodes into contact with tissue in the body cavity. A processor is configured to assess one or more individual contact quality indicators with respect to the contact between each of the multiple electrodes and the tissue, to compute one or more global contact quality measures based on the individual contact quality indicators of the multiple electrodes, to compare the one or more global contact quality measures to a predefined global contact quality criterion, and to display on a display screen an icon indicating whether the global contact quality measures satisfy the predefined global contact quality criterion.
