In certain embodiments, the catheter device further comprises an elongate tubular member, wherein the proboscis shaft is disposed within the elongate tubular member. In certain embodiments, the catheter device comprises a tissue surface engagement structure, which has a first configuration and a second configuration. In the second configuration, the tissue surface engagement structure presents a larger transverse profile in comparison to the first configuration. The tissue surface engagement structure may have any of various designs, including an expandable assembly and a hinged assembly. In certain embodiments, a deformable cushion is positioned at the distal end of the proboscis shaft. The deformable cushion comprises a pocket that is filled with a reshapeable material. In certain embodiments, the proboscis shaft comprises a longitudinally compressible portion.
