Offset bipolar electrode technology for minimizing collateral thermal damage

Presented is an offset electrode technology that minimizes collateral thermal damage for occlusion of vessels during surgery. This electrode configuration is conducive to applications where collateral thermal damage may compromise peripheral tissue sites and structures. Radiofrequency energy may be applied to specific surgical sites for coagulation where controlled thermal damage is required to hemostatically occlude blood vessels. The average width of collateral thermal damage is 0.58±0.43 mm using offset electrodes, indicating its promise for reducing unwanted peripheral tissue damage.
