1. Tissue cutting apparatus comprising:
- a pair of blades joined for relative movement in a scissors-like action between open and closed positions;
each of said blades comprising a tissue contacting surface for contacting tissue, said contacting surface of each blade including first and second spaced apart electrodes extending along said surface, said electrodes being adapted for connection to a voltage source having a pair of terminals of opposite polarity;
whereby current flow between said first and second electrodes of each blade promotes hemostasis in tissue contacting said surface.

Abstract
Bipolar electrosurgical scissors are disclosed having a pair of blades joined for relative movement in a scissor-like action between open and closed positions. At least one of the blades comprises a tissue contacting surface and first and second spaced apart electrodes extending along the surface. Current flow between the first and second electrodes promotes hemostasis in tissue contacting the surface. Preferably, each blade of the scissors includes first and second spaced-apart electrodes.

10. A method for simultaneously cutting and promoting hemostasis of tissue comprising:
-
providing tissue cutting apparatus comprising a pair of blades joined for relative movement in a scissor-like fashion between open and closed positions, each of said blades comprising a tissue contacting surface for contacting tissue located between said blades as said blades are moved together toward a closed position, the tissue contacting surface of each blade comprising first and second electrodes extending along the tissue contacting surface;
placing tissue to be cut between said blades in contact with said tissue contacting surface of each blade;
applying a voltage between the first and second electrodes of each blade so that current passes between said first and second electrode of each blade'"'"'s tissue contacting surface; and
closing the blades in a scissor-like action. - View Dependent Claims (11)
