摘要：
A method of dimensionally stabilizing a lumen of a multi-lumen device during manufacture wherein one or more minor lumens may contain a fluid that maintains patency of the one or more minor lumens without the need for a solid core within. The at least one second lumen tube may be in fluid communication with a fluid source during the manufacturing process, such as during extrusion and/or mesh overlay steps. Preventing collapse of the one or more minor lumens during manufacture using a fluid instead of a solid core allows the lumens to have any of a variety of shapes and configurations that would be difficult, cost prohibitive, or impossible for a solid core to be used. Also, obviating the need for a solid core within one or more lumens reduces cost and production complexity. The fluid may be a non-compressible liquid or a pressurized gas.
