摘要：
A method of making a multi-lumen catheter may include disposing an outer surface of a mandrel against an outer surface of a first catheter disposing a first heat shrink material around the first catheter and the mandrel heating the first catheter and the mandrel to form a U-shaped channel along the outer surface of the first catheter removing the first heat shrink material and the mandrel from the first catheter placing a second catheter into the U-shaped channel disposing a second heat shrink material around the first catheter and the second catheter such that the second catheter is retained within the U-shaped channel and heating the first catheter and the second catheter to cause reflow between the first catheter and the second catheter to form the multi-lumen catheter.
