1. A fluid duct, comprising:
a body extending along a central axis and defining a lumen configured to receive a first fluid extending therethrough, the body having an inner surface and an outer surface, wherein the central axis defines an axial direction along the central axis, a radial direction perpendicular to the central axis, and a circumferential direction oriented rotationally about the central axis; and
an elongate rib positioned on the inner surface of the body and formed from a wall, the wall extending radially inward from the inner surface of the body to protrude from the body into the lumen and extending continuously along at least a portion of the inner surface of the body in the circumferential direction, the wall defining a channel extending through the elongate rib in a primary direction, wherein the channel is configured to receive a second fluid and isolate the second fluid from the first fluid.
