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.

         35 . The surgical system of  claim 34 , further comprising a second monitor located along a second side of the operating table.  
     
     
         36 . The surgical system of  claim 34 , further comprising an operator control operably coupled to the energy source and located along a second side of the operating table.  
     
     
         37 . The surgical system of  claim 36 , wherein the operator control is a foot pedal.  
     
     
         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.    
     
     
         39 . The surgical system of  claim 38 , wherein the imaging probe is an intra-abdominal ultrasound probe.  
     
     
         40 . The surgical system of  claim 38 , wherein the laparoscope and the intra-abdominal imaging probe are operably coupled to at least one monitor, the at least one monitor being located along a first side of an operating table, and wherein the energy source is located adjacent the at least one monitor along the first side of the operating table.  
     
     
         41 . The surgical system of  claim 38 , wherein the energy source is selected from the group consisting of an RF energy source, a microwave energy source, a light energy source, and an acoustic energy source.  
     
     
         42 . The surgical system of  claim 40 , further comprising a second monitor located along a second side of the operating table.  
     
     
         43 . The surgical system of  claim 40 , further comprising an operator control operably coupled to the energy source and located along a second side of the operating table.
