摘要：
A feeding tube assembly having an improved feeding tube body composed of a tube wall having an external tube surface and an internal tube surface, a proximal end, a distal end separated from the proximal end by a length, and a distal tip region. The internal tube surface defines a feeding passageway extending the proximal end to the distal tip region. The tube body has a first cross-sectional profile from the proximal end to the distal end and at least a second cross-sectional profile from the distal end to the distal tip region. In the first cross-sectional profile, the external tube surface defines an external circumference and the internal tube surface defines a generally non-circular internal perimeter dividing the tube wall into one thin-walled portions and thick-walled portions. In the second cross-section profile, the external tube surface defines an external circumference and the internal tube surface defines an internal circumference.
