Abstract

An apparatus comprises a first jaw, a second jaw, a first handle, and a second handle. The second jaw is pivotally coupled with the first jaw. The first jaw and the second jaw are configured to grasp tissue. The jaws provide offset electrode surfaces that are operable to deliver bipolar RF energy to tissue grasped between the jaws. The apparatus is further operable to sever tissue. A lockout feature selectively prevents tissue severing, based on an energization state of the jaws.
