Abstract
Methods and systems are provided for necrosing and resecting tissue. A pair of electrodes are placed on opposed tissue surfaces, and radio frequency power is applied through the electrodes to necrose a tissue mass therebetween. After necrosis has been effected, the tissue may be resected along a plane within the necrosed region with minimum or no bleeding. The tissue mass may then be removed.
Claims28
A method for resecting tissue in a patient, said method comprising:
- engaging a first electrode structure and a second electrode structure against opposed surfaces of a tissue mass prior to resecting the tissue mass from the patient, wherein each electrode has a surface area of at least 1 cm.sup.2 ;
- applying high frequency power through said electrodes to said tissue mass, wherein said power is applied for a time and in amount sufficient to necrose said tissue mass between said electrode structures;
- stopping the high frequency power application;
- and
- resecting the tissue within the necrosed tissue mass after the tissue has been necrosed and the application of high frequency power stopped.
