    Abstract: The present invention provides systems and methods for applying RF energy to injured tissue, particularly the peritoneum, in order to prevent harmful post-surgical adhesions. One aspect of the invention is RF delivery systems (200) employing trocars (70), which are designed for use in laparotomies and laparoscopies. Another aspect of the invention is an RF delivery system comprising a surgical sheet (400) with one or more electrodes (401) for delivering the RF energy to the injured tissue resulting from conventional surgical incisions into the abdominal wall. Additionally, another aspect of the invention provides methods for controlling the treatment dosage of RF heat to the injured tissue using parameters such as treatment time, change in tissue temperature, and change in tissue impedance.

    Abstract: Apparatus for use with a blood vessel (10) of a subject includes (a) a longitudinal member (92) that has a proximal portion and a distal portion, and includes an electrode (94, 124) disposed at the distal portion, the distal portion being transluminally advanceable to the blood vessel; and (b) a control unit (100), in electrical communication with the electrode, and comprising circuitry (102). The circuitry is configured to: (a) during a dual- signal period, drive the electrode to apply a dual electric signal that has (i) an excitation component that has a frequency of 20 - 500 Hz, and (ii) an ablation component that has a frequency of 5 kHz - 1 GHz; and (b) during an ablation-signal period that is separate from the dual-signal period, drive the electrode to apply an ablation electric signal that has the ablation component but not the excitation component. Other embodiments are also described.
