Abstract:
A medical probe device for medical treatment of tissue in a body accessible through a natural body cavity comprising an elongate probe member having a proximal extremity and a distal extremity and a longitudinal axis and having a passageway therein extending from the proximal extremity to the distal extremity along the longitudinal axis, a stylet mounted in the elongate probe member, the stylet having proximal and distal extremities and including a conductive radio frequency electrode, handle means coupled to the proximal extremity of the elongate probe member, hand operable means carried by the handle means and connected to the stylet for causing advancement of the stylet through the passageway, a radio frequency generator coupled to the stylet for supplying radio frequency energy to the conductive radio frequency electrode, a return electrode electrically coupled to the radio frequency generator and in contact with the body, the distal extremity of the elongate probe member being in communication with the passageway and permitting the distal extremity of the stylet to be advanced out of the passageway sidewise at an angle with respect to the longitudinal axis and an optical viewing device mounted in the elongate probe member and having a distal extremity positioned in the distal extremity of the elongate probe member and having a field of view which permits viewing the distal extremity of the stylet as it is advanced from the passageway sidewise of the longitudinal axis.
