Abstract
An electrosurgical medical device for creating thermal welds in engaged tissue that provides general grasping and dissecting functionality. In an exemplary embodiment, at least one jaw of the instrument defines a tissue engagement plane carrying electrosurgical energy delivery means. The jaw assembly, in one mode of operation, can be used for general grasping and dissecting purposes wherein the jaws close in a non-parallel manner so that the distalmost jaw tip only engage tissue with little movement of the actuator lever in the handle of the instrument. In another mode of operation, the jaw assembly closes close in a parallel manner under very high compression to enable tissue welding.
