Fluid-assisted medical devices, systems and methods
First Claim
1. A tissue grasping device comprising:
- a tip portion including a first jaw and a second jaw, at least one of the jaws being movable toward the other jaw;
the first jaw including a first tissue grasping surface and the second jaw including a second tissue grasping surface, the tissue grasping surface of each jaw having a length defined by proximal and distal ends, a width defined by edges and further comprising an electrically insulative surface;
first and second electrodes being connectable to different terminals of a radio frequency generator to generate electrical current flow therebetween, the first electrode having a first electrode surface and the second electrode having a second electrode surface;
at least one fluid passage being connectable to a fluid source;
one of the first and second electrode surfaces being located on one or the other of the jaws separated from one edge of the tissue grasping surface and the other of the electrode surfaces being located on one or the other of the jaws separated from the other edge of the tissue grasping surface.

Abstract
Surgical devices, systems and methods for treating tissue are provided. An exemplary surgical device comprises a tip portion including first and second jaws each having a tissue grasping surface, at least one of the jaws being movable toward the other jaw. The tissue grasping surface of each jaw has includes an electrically insulative surface. The device also includes first and second electrodes connectable to different terminals of an RF generator to generate electrical current flow therebetween, with each of the electrodes having an electrode surface. One of the electrode surfaces is located on one of the jaws separated from one edge of the tissue grasping surface, and the other of the electrode surfaces is located on one or the other of the jaws separated from the other edge of the tissue grasping surface. The device also includes at least one fluid passage being connectable to a fluid source.
