Abstract
A nutritive catheter is assembled by attaching a head to the distal end of a main tubing having a duct therethrough, the head being formed from a composition comprising a flexible synthetic resin and a finely divided metal material in a ratio by volume of resin to metal material of at least 2 and having a specific gravity of at least 2. An opening is provided in the head in communication with the tubing duct.
