ABSTRACT:
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.
