Abstract:
An electrosurgical device for ablating tissue, the device comprising:a first handle portion; a second handle portion; a jaw comprising a first jaw arm and a second jaw arm, the first and second jaw arms movable between a disengaged configuration and an engaged configuration by relative movement of the first and second handle portions, the first jaw arm having a first ablative portion on an inner face and the second jaw arm having a second ablative portion on an inner face, the first and second ablative portions of the first and second jaw arms each configured in at least one convex portion for grasping tissue between the first and second jaw arms when the first and second jaw arms are in the engaged configuration, the first and second ablative portions each having a surface comprising: an elongated insulator extending along the jaw arm; and an elongated electrode centrally located within the ablative portion of the jaw arm and in a partially recessed position with respect to the elongated insulator, the elongated electrode of the first jaw arm aligned in a substantially parallel spaced relationship with the elongated electrode of the second jaw arm when the jaw arms are grasping tissue in the engaged configuration; and a first electrical conductor extending to the electrode of the first jaw arm; and a second electrical conductor extending to the electrode of the second jaw arm, first and second electrical conductors adapted to provide radiofrequency energy to the electrodes such that the electrodes are in a bipolar configuration.
