Abstract: An electrosurgical probe includes an elongated shaft forming a lumen extending along a longitudinal axis from a proximal end portion to a distal end portion. An insulating layer is disposed on the distal end portion of the elongated shaft. A supply electrode is disposed on the insulating layer over a distal extent of the elongated shaft. A return electrode includes an exposed portion of the elongated shaft proximal of the insulating layer.

Abstract: An electrosurgical probe includes an elongated tubular shaft including a lumen extending along a body from a proximal shaft portion to a distal shaft portion. The distal shaft portion forms an active electrode as a first exposed conductive portion at a distal extent of the elongated shaft. A first insulating layer extends over the body from the proximal end portion to the distal end portion. A conductive layer extends over the first insulating layer and terminates proximal of the first insulating layer. A second insulating layer extends over the first insulating layer and the conductive layer and terminates proximal of a distal conducting portion of the conducting layer forming a return electrode.

Abstract: An apparatus and method provide for the delivery of an ablation treatment by supplying a control signal to supply electrode of an ablation device disposed at the distal end portion of an elongated shaft. A lumen extends along a longitudinal axis of the shaft. The supply electrode forms an electrode face laterally directed from the longitudinal axis and through which an aperture extends in connection with the lumen. The electrode face forms an ovular shape having a first major axis that extends parallel to the longitudinal axis. An insulator separates the supply electrode from a return electrode, and a transition passage of the lumen extends though the insulator along an arc-shaped path.

Abstract: Examples of systems and methods described herein may utilize augmented reality headsets and removal resection guide markers in generating intra-operative plans and providing surgical guidance. A system may include a marker with an insertion member and a resection guide to be attached to a body part. The resection guide includes a slot that receives either the insertion member or a resection device. A system may guide placement of the resection guide using the marker removably attached to the surgical resection guide, such as by being inserted into the slot. After removal of the marker, the slot may guide a cutting device to cut along a resection plane.

Abstract: A jaw movement mechanism for surgical tools has improved mechanical efficiency and other advantages. The jaw movement mechanism controls the orientation and position of a movable jaw relative to a fixed jaw through a range of movement of the movable jaw. The jaws maintain a parallel orientation throughout a portion of the range of movement of the movable jaw. The jaws maintain an angular relationship throughout a portion of the range of movement of the movable jaw.
