Abstract: A method of producing a multi-lumen elongate body for a medical device. Unlike known methods requiring a solid core of material inserted into each lumen to maintain patency of the lumens during manufacture, the present method obviates the need for a solid core within one or more minor lumens, which saves cost and production complexity. One or more material overlay and mesh overlay steps may be used to produce the multi-lumen elongate body, but only the main lumen may include a solid core therein during all manufacturing steps. The one or more minor lumens may each be defined by a lumen tube having a sufficient stiffness to withstand external pressure during all manufacturing steps without the need for a solid core within.

Abstract: A method and system for manufacturing a multi-lumen device that includes extruding a first layer of 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, depositing a mesh layer over the first layer of material along the entire length of the elongate body, and extruding a second layer of material over the mesh layer along at least a portion of the length of the elongate body. The length of at least 100 feet may be considered a first length, the method further comprising cutting the elongate body into a plurality of shortened elongate bodies having a usable length, such as between approximately two feet and approximately six feet.
