摘要： An ablation system comprising a source of electrical ablation energy having first, second and third power outputs it is disclosed. A first conductor is coupled to the first power output on the source of electrical energy. A second conductor is coupled to the second power output on the source of electrical energy, the source of electrical energy creates a first output ablation voltage between the first and second power outputs. The first output ablation voltage varies between a first higher average value during a first period of time and a first lower average value for a second period of time. The first lower average value is greater than or equal to zero. A third conductor is coupled to a third power output on the source of electrical energy. The source of electrical energy creates a second output ablation voltage between the first and third power outputs. The second output ablation voltage varies between a second higher average value during a third period of time and a lower average value for a fourth period of time. The lower average value is greater than or equal to zero. An ablation probe is coupled to the first conductor.

摘要： A method of ablating a uterine fibroid using a particular trocar is disclosed. The trocar comprises a plurality of ablation stylets. The trocar is adjustable to assume a plurality of configurations, each of the configurations having the stylets extended to a different extent from the trocar. A region to he ablated is imaged. The size of the region to be ablated is noted. The size of the region to be ablated is compared to a matrix of known ablation regions, each of the known ablation regions being associated with one of the configurations of the particular trocar. The region to be ablated is associated with a most nearly matching known ablation region by comparison of the region to be ablated to the known ablation regions. A trocar is inserted into the uterine fibroid at a position, which more closely matches the position of the particular trocar with respect to the known ablation region. The stylets are deployed from the trocar to an extent corresponding to the configuration.

摘要： The inventive method for ablating a tissue mass associated with a human or animal patient being treated comprises positioning an ablating electrode in a tissue mass to be ablated. A plurality of return electrodes are positioned on the patient. Electrical energy is applied between the return electrodes and the ablating electrode. The temperature of the return electrodes is measured to generate a temperature measurement signal which is used to control ablation current through the return electrodes.

摘要： A method of ablating a uterine fibroid using a particular trocar is disclosed. The trocar comprises a plurality of ablation stylets mounted for movement from within the trocar to positions extending from the trocar. The trocar is adjustable to assume a plurality of configurations, each of the configurations having the stylets extended to a different extent from the trocar. A region to be ablated is imaged. The region may correspond to all or a portion of a uterine fibroid. The size of the region to be ablated is noted. The size of the region to be ablated is compared to a matrix of known ablation regions, each of the known ablation regions being associated with one of the configurations of the particular trocar, and each of the known ablation regions being associated with a position of the trocar relative to the known ablation region. The region to be ablated is associated with a most nearly matching known ablation region by comparison of the region to be ablated to the known ablation regions. A trocar of the design of the particular trocar is inserted into the uterine fibroid at a position, with respect to the region to be ablated, which more closely matches the position of the particular trocar with respect to the known ablation region. The stylets are deployed from the trocar to an extent corresponding to the configuration associated with the most nearly matching known ablation region.

摘要： A method for treating pelvic tumors, such as uterine leiomyomata, includes inserting an ablation apparatus into a pelvic region and positioning the ablation apparatus either proximate or into a pelvic tumor. The method further includes using a laparoscope and an imaging device, such as an ultrasound machine, to confirm the location of the pelvic tumor and placement of the ablation apparatus. Various ablation apparatuses may be used, including those with multiple needles or deployable arms that are inserted into the pelvic tumor and those without arms. The method further includes delivering electromagnetic energy or other energy through the ablation apparatus to the pelvic tumor to ablate the tumor. A surgical system for ablating pelvic tumors is also provided.
