The present invention is a bolus for an enteral feeding tube, or catheter, that is capable of being used in an over-the-wire intubation procedure as well as other intubation procedures. The bolus has a generally tubular body defining a sidewall, a proximal end tube opening capable of being connected to a distal end of the enteral feeding tube, and a generally rounded terminal end having a flattened tip. The bolus includes a fluid opening within the sidewall of the bolus between the proximal end opening and the terminal end of the bolus. An interior surface of the sidewall opposite the fluid opening is curved and slopes upwardly toward a distal end of the fluid opening. The curved interior surface and the fluid opening configuration allows for fluid flow that approximates the fluid flow rate characteristics of an open-ended tube. The fluid opening is biased toward the terminal end of the bolus thereby defining an elongated collar portion adjacent the proximal end tube opening of the bolus. The terminal end of the bolus has an aperture therethrough that forms a stylet passage in communication with the fluid opening. The stylet passage is sized to allow a stylet to pass therethrough when the tube is used in an over-the-wire intubation procedure.
