1. A tubing junction assembly comprising:
a body including a head portion and a base portion extending longitudinally from the head portion, the body having an outer surface, the head portion defining a proximal end portion of the body, the base portion defining a distal end portion and an intermediate portion interposed between the proximal end portion and the distal end portion of the body, wherein at least a portion of the outer surface of the body at the intermediate portion defines a diameter that decreases from the head portion to the base portion; and
a collar coupled to the body, the collar having a head portion, a base portion extending longitudinally from the head portion, and an inner surface defining a passage that extends between the head portion and the base portion, the head portion comprising a proximal end portion and a distal end portion, and the inner surface at the head portion of the collar defines a diameter that decreases from the proximal end portion to the distal end portion of the head portion, wherein the diameter of the outer surface of the body along the intermediate portion is approximately equal to the diameter of the inner surface of the head portion of the collar,
wherein a tubing having a proximal end portion, a distal end portion, an outer surface, and an inner surface defining a lumen extending from the proximal end portion to the distal end portion is stretched over the outer surface of the body with the proximal end portion of the tubing stretched over at least a portion of the outer surface of the body at the intermediate portion, and wherein the inner surface of the collar is sleeved over at least a portion of the outer surface of the tubing and coupled to the collar such that the proximal end portion of the tubing is compressed between the body and the collar.
