Abstract: A bipolar tunneling tool is configured to separate tissue adhesions and tunnel. The bipolar tunneling tool includes a handle, a tunneling shaft, a return electrode, an optical window, an active electrode, and an insulative housing. The tunneling shaft extends from the handle. The return electrode is disposed proximate a distal end of the tunneling shaft. The optical window is disposed proximate the distal end of the tunneling shaft, the optical window defining a channel. The active electrode is at least partially disposed within the channel. The active electrode is configured to dissect a tissue and cauterize the tissue. The insulative housing is configured to electrically insulate the active electrode from the return electrode.

Abstract: In some examples, a tool for, e.g., creating a sub-sternal tunnel in a patient or other use, is described. The tool may include a handle and a tunneling shaft coupled to the handle. The tunneling shaft extends from a proximal end to a distal end, and at least a portion of the tunneling shaft extends in a curved orientation between the first end to the distal end. The distal end of the tunneling shaft includes a cutting tool having a sharp edge. The cutting tool is moveable from a recessed position in which the sharp edge of the cutting tool is recessed into the distal end of the tunneling shaft to a deployed position in which the sharp edge of the cutting tool extends beyond the distal end of the tunneling shaft in the deployed position, e.g., to cut pericardium, scar tissue, and/or connective tissue with the sharp edge.
