First Claim
Patent Images
1. 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 cm2 ;
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.

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.
