1. A visualization catheter comprising:
an elongate shaft including a proximal end, a distal end, and a central axis defined therebetween;
a cap element attached to and extending distally from the distal end of the shaft, the cap element defining an aperture and having a visualization element disposed within the aperture; and
wherein an offset balloon is coupled to the distal end of the shaft, and wherein the offset balloon completely encapsulates the cap element and the distal end of the shaft such that the offset balloon defines a distal terminal end of the visualization catheter, wherein the offset balloon defines a center point offset relative to the central axis of the shaft;
wherein the offset balloon includes a body region and a cylindrical neck region coupled to the distal end of the elongate shaft, wherein the cylindrical neck region is coaxial with the central axis of the shaft and the body region defines a center point that is offset relative to the central axis of the shaft, wherein the body region extends from the cylindrical neck region with an outer extent of a first side of the body region aligned with an outer extent of the cylindrical neck region, and an outer extent of a second opposite side of the body region extending radially outward from the cylindrical neck region.
