Abstract: A computer implemented method comprises activating a control mechanism on a catheter handle in a first direction with respect to a user to steer a distal end of a catheter within a body in a second direction while the catheter handle is in a first rotational position. The control mechanism includes a first indicator associated with the first direction. The computer implemented method also includes obtaining an image from the distal end of the catheter of a tissue region of interest within the body and calibrating a first rotational motion of the catheter handle with a rotational motion of the image. With the catheter handle in a second rotational position that is different than the first rotational position, the control mechanism activated in the first direction with respect to the user moves the distal end of the catheter in the second direction.

Abstract: A surgical cannula includes a camera disposed at the distal end to permit visualization of tissue. A hinge pivotably couples the camera to the cannula and permits the camera to pivot from a first position at the distal end of the cannula to a second position different than the first position at the distal end of the cannula. Some implementations include a pointed distal tip that carries the camera. Some implementations include two cameras posed back to back.

Abstract: Electrode placement and connection systems are described which allow for the electrical connection and maintenance of one or more electrodes positioned on a substrate which is subjected to a variety of mechanical stresses. Electrodes may also be formed on flexible circuit assemblies integrated within or along the hood. The circuit assemblies may also provide structural support to the hood during delivery and/or deployment. Such a system may include an imaging hood having an aperture through which transparent fluid is flowed and one or more electrodes positioned along or about the hood. As the hood is configured between a low-profile and opened configuration, these electrodes may remain electrically coupled despite the mechanical stresses subjected to the electrodes and the connections thereto.
