Methods of manufacturing a multi-lumen device

A method of producing a multi-lumen medical device, the method comprising:

• extruding a layer of a first material over a first lumen tube and at least one second lumen tube to form an elongate body having a length of at least 100 feet, a first lumen, and at least one second lumen;
• depositing a mesh layer over the layer of first material;
• extruding a layer of a second material over the mesh layer, each of the first lumen tube and the at least one second lumen tube at least one of:
• being composed of a third material that has a higher durometer than the first material;
• and
• containing a fluid therein.

A system for producing a multi-lumen elongate body, the system comprising:

• a first extruder configured to extrude a layer of first material to form an elongate body with a first lumen and a second lumen, the elongate body having a length of at least 100 feet;
• a machine configured to deposit a mesh layer over the layer of first material along the entire length of the elongate body;
• a second extruder configured to extrude a layer of second material over the mesh layer along at least a portion of the elongate body;
• and
• a source of fluid in fluid communication with the second lumen during extrusion of the layer of first material, deposition of the mesh layer over the layer of first material, and extrusion of the layer of second material over the mesh layer.
