A medical device, such as a catheter or feeding tube, has a tube element to the front end portion of which a weighted bolus tip is connected. The bolus tip may have a lumen provided with an open front end and communicating with the lumen of the tube, or it may be of solid cross-section in which case outlet openings for the fluid passing through the device are so positioned that it is impossible for a stagnating pool of the fluid to form in the device (to avoid the growth of micro-organisms). The tip itself is produced by mixing powdered metal with a synthetic plastic binder; the mixture is then given the desired shape by casting or molding and thereafter is polymerized to convert the shaped body into a unitary element having no free metal. This renders it impossible for any of the metal powder to spill.

A medical device, particularly a catheter or feed tube, comprising a tube having a passage and being provided with a trailing end portion adapted to receive a flowable substance and a leading end portion; weighting means at said leading end portion and comprising an element composed of a mixture of powdered metal and synthetic plastic binder therefor, said element having two spaced ends and a channel which is open at said ends and communicates with said passage so that the flowable substance can pass from said tube into and through said element without hindrance; and outlet means for egress of flowable substance from said passage of said tube.
