1. A method for delivering energy to a selected tissue, said method comprising:
- clamping the tissue between a first jaw and a second jaw, wherein the jaws each have an energy delivery surface and are adapted to open and close relative to each other with a selectable degree of jaw closure between the first and second jaw;
delivering energy to the tissue through at least one of the jaws in at least a first mode and a second mode; and
selecting the first mode, the second mode, or both based on an operational parameter;
wherein the first mode of delivering energy substantially dehydrates and reduces the cross-section of the tissue and the second mode of delivering energy welds the tissue.

Abstract
An electrosurgical working end and method for sealing and transecting tissue are provided. An exemplary electrosurgical working end has openable-closeable first and second jaws for progressively clamping a selected tissue volume. A method of the invention comprises applying electrosurgical energy to the tissue in either a first mode or a second mode based on the degree of jaw closure.

13. An electrosurgical instrument, comprising:
-
an instrument body; a working end on the instrument body having a first jaw and a second jaw, wherein the jaws each have an energy delivery surface and are adapted to open and close relative to each other with a selectable degree of jaw closure between the first and second jaw; and a control system configured to activate the energy delivery surfaces in a first mode, a second mode, or both based on an operational parameter; wherein the first mode of delivering energy substantially dehydrates and reduces the cross-section of the tissue and the second mode of delivering energy welds the tissue. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
