Abstract

Enteral feeding tubes are formed from the polymeric composition of, by wt, (a) 10 to 20% of a thermoplastic elastomeric block copolymer (e.g. of monovinyl arene and conjugated diene blocks) and (b) 0.1 to 12% of a linear polysiloxane (e.g. a silicone oil) of kinematic viscosity 20-10<6> cst., which mixture is known to be used for medical tubing, and (c) 80 to 90% of tungsten powder, and optionally a polypropylene binder. The stem of the tube may be formed without the tungsten (c),which must be present in the bolus at the distal end of the tube; the bolus (48) and a female connector (44) preferably being insert moulded onto the stem (42). The bolus may have a plurality of holes to the exterior each connected to a central bore. <IMAGE>
