Surgical device for clamping, ligating, and severing tissue
First Claim
1. A surgical device for severing tissue, the surgical device comprising;
- a first shaft having a first internal lumen and a first slot disposed at a distal end;
a clamp slidingly disposed in the first slot between open and closed positions to capture tissue in the first slot, the clamp having a clamping surface disposed at a distal end;
at least one electrode for applying RF energy to the tissue captured in the first slot;
a cutting blade slidingly disposed in the first slot between open and closed positions, the cutting blade having a cutting edge to sever the tissue;
first actuation means for actuating the clamp between the open and closed positions; and
second actuation means for actuating the cutting blade between the open and closed positions.

15. A method for severing tissue, the method comprising:
-
providing a surgical device comprising;
a shaft having an first internal lumen and a slot disposed at a distal end;
a clamp slidingly disposed in the slot between open and closed positions to capture tissue in the slot, the clamp having a clamping surface disposed at a distal end;
at least one electrode for applying RF energy to the tissue captured in the slot;
