<p>A thin walled microtube is formed by providing a continuous elongated member (32) having an outer surface. The member (32) is at least partially formed of a water soluble material. A coating material (75) is provided. The coating material (75) may be a silicone compound that is curable such that the coating material cures into a substantial non-porous silicone. The outer surface of the elongated member (32) is coated with a coating material (75) so as to form a substantially uniform and continuous layer of coating material on the outer surface. The layer of coating material is cured so as to form a substantial uniform and continuous layer of substantially non-porous silicone on the outer surface. The elongated member (32) is partially dissolved using water and purged from the silicone layer, such that an elongated tube (30) of substantially non-porous silicone is formed.</p> |
