Abstract
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.

27. A surgical system for ablating pelvic tumors in a patient, the system comprising:
-
an ablation device for insertion into a pelvic region of a patient;
an energy source coupled to the ablation device for providing energy to the ablation device;
a laparoscope for insertion into the patient; and
an intra-abdominal imaging probe for observing a location of the ablation device within the pelvic region of the patient. - View Dependent Claims (28, 29, 31, 32, 33, 34, 35, 36, 37)

38. A surgical system for ablating pelvic tumors in a patient, the system comprising:
-
an ablation device for insertion into a pelvic region of a patient, wherein the ablation device includes a plurality of electrodes;
an energy source coupled to the ablation device for providing energy to the ablation device;
a laparoscope for insertion of the plurality of electrodes within a pelvic tumor of the patient to avoid contact with normal tissue outside of the pelvic tumor; and
an intra-abdominal imaging probe for observing a location of the plurality of electrodes completely within the pelvic tumor of the patient. - View Dependent Claims (39, 40, 41, 42, 43, 44)
