Abstract (en)
[origin: WO2013079961A1] Multitube catheter and method for making the same are provided. The assembly includes two (T1,T3) tube fused together to form one catheter tube shaft. Each tube has (112,113) one lumen extending longitudinally through the catheter from its distal end to its proximal end. The tubes are fused together by use of heat & pressure. Heat and pressure can be generated by heat Shrinkable tube slides over a segment of catheter tubes while metallic mandrels are passed through each tube lumen to protect the lumens during fusion. The heat Shrinkable tube will shrink once heat is applied. The heat Shrinkable tube will shrink and apply the required pressure over the catheter tubes. Continual heating will melt and re -shape the catheter tubes inside the heat Shrinkable tube while the letter will not be affected due to its high melting temperature. After cooling, the heat Shrinkable tube is to be removed, the metallic mandrels are pulled back and the tubes forming the united catheter tube. One or more of the tubes can be of different hardness, material and/or color. The difference will provide pressure resistant lumen (s), overall catheter elasticity and/or identification. Distal end of the united catheter tube can be split free floating, stepped or tapered tipped. The proximal segment (none fused) will form catheter extension legs.
