A feeding tube assembly, the assembly comprising: a feeding tube body including 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 defining a feeding passageway extending from an opening at the proximal end of the tube body to an opening at the distal tip region, the feeding tube body having: a first cross-sectional profile from the proximal end to the distal end, the first cross-sectional profile characterized by the external tube surface defining an external circumference and by the internal tube surface defining a generally non-circular internal perimeter; and at least a second cross-sectional profile from the distal end to the distal tip region, the second cross-section profile characterized by the external tube surface defining an external circumference and by the internal tube surface defining an internal circumference; a base located at the proximal end of the feeding tube body, the base being deployed outside a human body and defining an opening to the feeding passageway, the base having a first end and a second end; and a retention member located at a distal end of the feeding tube body, the retention member being deployed in a lumen of a human body; wherein the distal tip region has a first portion and a second portion, the first portion being proximal to the second portion and characterised by the distal tip region having a generally uniform and relatively greater wall thickness along the circumference of the first portion and a generally uniform and relatively lower wall thickness along the circumference of the second portion. a feeding tube body including 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 defining a feeding passageway extending from an opening at the proximal end of the tube body to an opening at the distal tip region, the feeding tube body having: a first cross-sectional profile from the proximal end to the distal end, the first cross-sectional profile characterized by the external tube surface defining an external circumference and by the internal tube surface defining a generally non-circular internal perimeter; and at least a second cross-sectional profile from the distal end to the distal tip region, the second cross-section profile characterized by the external tube surface defining an external circumference and by the internal tube surface defining an internal circumference; a base located at the proximal end of the feeding tube body, the base being deployed outside a human body and defining an opening to the feeding passageway, the base having a first end and a second end; and a retention member located at a distal end of the feeding tube body, the retention member being deployed in a lumen of a human body; wherein the distal tip region has a first portion and a second portion, the first portion being proximal to the second portion and characterised by the distal tip region having a generally uniform and relatively greater wall thickness along the circumference of the first portion and a generally uniform and relatively lower wall thickness along the circumference of the second portion. a first cross-sectional profile from the proximal end to the distal end, the first cross-sectional profile characterized by the external tube surface defining an external circumference and by the internal tube surface defining a generally non-circular internal perimeter; and at least a second cross-sectional profile from the distal end to the distal tip region, the second cross-section profile characterized by the external tube surface defining an external circumference and by the internal tube surface defining an internal circumference; a base located at the proximal end of the feeding tube body, the base being deployed outside a human body and defining an opening to the feeding passageway, the base having a first end and a second end; and a retention member located at a distal end of the feeding tube body, the retention member being deployed in a lumen of a human body; wherein the distal tip region has a first portion and a second portion, the first portion being proximal to the second portion and characterised by the distal tip region having a generally uniform and relatively greater wall thickness along the circumference of the first portion and a generally uniform and relatively lower wall thickness along the circumference of the second portion.
