摘要： A process and apparatus for producing an elongated body changing in elastic modulus longitudinally thereof with use of polymers without resulting in variations in the outside and inside diameters of the body even when the polymers are different in extrusion characteristics or swelling characteristics. The apparatus may include a feeder 1 for extruding a first polymer in a molten state and a feeder 2 for extruding a second polymer, which is different from the first polymer in elastic modulus and similarly in a molten state. The feeders alternately discharge the respective polymers, which are continuously fed to a long-land die 5 along with a lubricant supplied from a lubricant applicator 4. The polymers are formed into the desired shape and cooled in the die 5, and thereafter extruded.

摘要： A method for producing a thermoplastic polyurethane elastomer tube where the temperature of the mandrel and the extrusion pressure used for extruding a thermoplastic polyurethane elastomer are determined before preparing the tube. The temperature of the mandrel and the extrusion pressure are set to overlap two predetermined temperature ranges. One temperature range permits hot drawing of the tube preform, and the second temperature range provides a tube preform free from the occurrence of bubbles on its surface. After the two temperature and extrusion pressure ranges are determined, a thermoplastic polyurethane elastomer is extruded on the periphery of a heated mandrel under pressure using a mandrel temperature and extrusion pressure where the two predetermined ranges overlap. Thereafter, the mandrel is pulled out to provide a tube preform, and the tube preform is hot drawn to produce a tube having a desired outer diameter. The method of the present invention can provide a thermoplastic polyurethane elastomer tube having a fine hot drawability while overcoming poor appearances due to the occurrence of bubbles or granular structure. In addition, the thermoplastic polyurethane elastomer tube has a stable quality that can be continuously produce, thus increasing the yield thereof.

摘要： A catheter consists of a torque transmitting portion which has rigidity sufficient for torque transmission and a flexible portion made of a material having a glass transition temperature for giving rigidity before insertion and flexibility after insertion. The torque transmitting portion maintains torque transmitting ability before, during and after insertion. The flexible portion maintains appropriate rigidity before and during insertion, which enables easy insertion, and gains flexibility after insertion by the body heat, which avoids hurting of the vulnerable insertion walls. Further, the torque transmitting portion may have a structure wherein a reinforcement of a coil or a braid of linear metal wires, specifically flat rectangular wires, is attached thereto to afford torque transmitting ability. Catheters having various functions and structures can be easily manufactured by extrusion-molding, or the like.
