This invention relates generally to a tubular medical device, and more particularly to a tubular medical device for fluid feeding to or fluid drainage from a body cavity. The invention describes both a device and a method of making a device that comprises an elongated flexible primary tube forming a lumen having an open end, a secondary tube concentrically surrounding and spaced from the primary tube and extending between the open end and a position spaced from the open end. The primary and secondary tubes have an integral joining portion at the open end. The primary and secondary tubes form a chamber that is sealably closed and filled with a heavy metal so that a weighted tip element, or bolus is formed. Alternatively, the chamber may be pressurized and expanded to form a balloon element by way of a side tube affixed to the primary tube and connected at one end to a source of pressurized air and at the other end to a position within the chamber.
