The stiffening structures may be disposed on or be continuous with, for example, an exterior surface, an interior lumenal surface, within a wall of the catheter shaft, or some combination thereof. The stiffening structures described herein are directed to biasing the catheter shaft in the region of a side port aperture in a straight or curved configuration that resists undesired flexure in the region of the side port aperture.
A catheter, comprising an elongate shaft, said elongate shaft comprising:
The catheter of claim 28, comprising the at least one cannula being disposed within the wall from a point proximal of the aperture to a point distal of the aperture, with an opening in the cannula corresponding to the aperture.
