Abstract: A device for visualizing a surgical procedure in an ear may include a handle, a visualization shaft extending from the handle and including a distal end disposed at an angle that is not perpendicular to a longitudinal axis of the visualization shaft, and a rotation mechanism connecting the visualization shaft to the handle. The rotation mechanism allows the visualization shaft to rotate around the longitudinal axis relative to the handle. The device also includes an imaging sensor at a distal end of the visualization shaft and a light source at the distal end of the visualization shaft. The imaging sensor and the light source are positioned at the angle of the distal end relative to the longitudinal axis of the visualization shaft.

Abstract: A scaffold is mounted on a balloon of a balloon catheter. The scaffold has closed cells which deform upon balloon expansion and generate forces that cause struts or other components of the scaffold to deflect outwardly to a diameter that is greater than the inflated diameter balloon. The deflected struts apply forces to fracture plaque of other hardened lesions and also form an annular gap surrounding the balloon to provide for bypass flow of blood or other body fluids. A sheath may be located over the deflected struts to protect adjacent tissue structures from the deflected struts and/or to further define the gap.
